By proper choice of materials for f ac- ings and core, constructions with high ratios of stiffness to weight can be achieved. Sandwich construction is also economical, for only small amounts of the relatively expensive facing ma- terials are used and the core materials are usu- ally inexpensive. · The materials are posi- tioned so that each is. usoo to its best advantage. Specific nonstructural advantages can be in- corporated in a ·sandwich construction by proper selection of facing and core materials. An impermeable facing can be employed to act as a moisture barrier for a wall or roof panel in a house; an abrasion-resistant facing can be used for the top facing of a floor panel; and decorative effects can be obtained by using panels with plywood or plastic facings for walls, doors, tables, and other furnishings. Core ma- terial can be cho~en to provide thermal insula- tion, fire resistan~e, and decay re~istance. Care must be use<t in choice of sandwich components to a,·oid problems in sound trans- mission from room· to ·room because of the light weight of the construction. Methods of joining panels to each other and to other structures must be planned so that the joints function properly and allow for possible dimension change due to temperature and moisture change. The components of the sand\\·irh construc- tion should be compatible with senice require- ments. Moisture-resistant facings, cores. an<l adhesiYes shoul<l be· employed if the con::trur- tion is to be expoRed to adverse moisture condition~. Similarly. heat-resistant or decay- resistant facing-s, cores. and adhe::i\'es should be used if exposure to ele\·ate<l temperature:-or decay organisms is expected. •run, N •3111"1,, Agure 12-1.--.A cvtcrwcry Mction of sandwich constrvctlon with plywood facings and a paper honeycomb core. FABRICATION OF SANDWICH PANELS Facing Materials One of the adrnntages of sand,rich construc- tion is the great latitude it proddes in choice of facings and the oppJ,tunity to use thin sheet materials because of the nearly contin- uous support by the core. The stiffness, stabil- ity, and, to a large extent, the strength of the s~ndwich are determined by the characteristics of the facings. Some of the different facing materials used include plywood, single ,·eneers or plywood oYerlaid with a resin-treated paper. hardboard, asbestos cement board. particle- board, fiber-reinforced plastics or laminates. \'eneer bonded to metal, and . ..such metals as aluminum, enamele<l steel, stainless steel. nl' magnesinnr.

Special presses are needed for sand- wich panel manufacture to avoid crushing lightweight cores; pressures required are usu- ally lower than can be obtained in the range of good pressure control on presses ordinarily _used for plywood or plastic manufacture. Be- cause pressure requirements are low,. however, simple and perhaps less costly presses could be used. Continuous roller presses or fluid pres- sure equipment may also be suitable. Certain 12-3 tj r .f d tt L ( i \ ( •. -:: ., . apecial problems ariae in the preuing of sand- , · , wich' panels. but their manufacture is basically ='. " not ·complicated. -~ . Adhesives must be set~ to provide the necessary joint strength and permanence, as well as the working properties needed for fab- rication of the panels. The facing materials, especially if metallic, may need special surface preparation before the adhesive is applied. In certain s.andwich panels, loading rails or edgings are placed between the facings at the time of &UeUlbly. Special fittings or equip.. m•t, such ·as heating coils, plumbing, or elec- . .... . trical wiring condu!t, can be placed more eas- . .-,-'· : .fly in the panel dunng manufacture than after ·1 . :,...ft fa completed. Some of the most persistent difflcu1ties in the use of sandwich panels are caused by the necessity for edges, inserts, and connectors for panels. In some cases, the problem involves tying together thin facing materials without causing severe stress concentrations; in other cases, such as furniture manufacture, the prob- ·lem ia "showthrough" of core or inserts through decorative facings. These difficulties ., are minimized by a choice of materials in which the rate and degree of differential di- mensional movement between core and insert are at a minimum. / f / STRUCTURAL DESIGN OF SANDWICH . CONSTRUCTION The structural design of sandwich construc- tion may be compared to the design of an I- beam; the, facings of the sandwich represent the flanges of the I-beam, and the sandwich core represents the I-beam web. The core of the sandwich, through the bonding adhesive, carries shearing loads and suppQ_ft;s the thin -racings against lateral wrinkling caused by compressive loads in the facings. In general, the procedure is to provide fac- ings thick enough to carry the compression and tension stresses, and then to space the facings with a core thick enough to impart stiffness and bending strength to the construc- tion. The core should be strong enough to carry the shearing loads specified for the design. The construction should be checked for possible buckling, as for a column or panel in compres- sion, and for possible wrinkling of the facings. The core. material itself is assumed to con- tribute nothing to the stiffness of the sand- wich construction, because it usualJy has a low modulus of elasticity. The facing moduli of ,P14sticity are usually at least 100 times as " . ' jj_ . ,;~i· great as the core modulus of elasticity. The · :~:'t~ · core material may also have a small shear mod-·:·=,'• ulus. This small shear modulus causes increased ~~ : · deflections of sandwich constructions subjected to bending and decreased buckling loads of columns and edge-loaded panels, compared to constructions in which the core shear modu0 lus is large. The effect of this low shear modu- lus is greater for short beams and columns . and small panels than it is for Jong beams and columns and large panels. The bending stiffness of sandwich construc- .tion having facings of equal or unequal thick- ness is given by: D E1tiEa~h;• • E1t1 + E2ti (12-1) where D is the stiffness per unit width of sand- wich construction (product of modulus-of elasticity and moment of inertia of the cross sec- tion); E" E2-are the moduli of elasticity of fac--l ings 1 and 2; ti, ta are the facing thicknesses; l and k is the distance between facing centroids. The shear stiffness of sandwich, per unit width, is given by: / (12-2) where Ge is the core shear mddulus associated with distortion of the plane perpendicular to sandwich facings and parallel to the sandwich length. The bending stiffness, D, and shear stiff- ness, U, of sandwich construction are used to compute deflections and buckling loads of sand- wich panels. The general expression for the deflection of flat sandwich beams is gh-en by: !Py = _ M,, + 1 dSr dx2 D U dx (12-8) where y is deflection ; x is distance along the beam, M,. is bending moment at point x (per unit beam width) ; S,. is shearing force at point x (per unit beam width); D is flexural stiff- ness; and U is shear stiffness. Integration of this formula leads to the following general expression for deflection of a sandwich beam: k,J>a.:' k,Pa y = ~ + -yr-(12-4) )'·here II is deflection, P is total beam load per unit beam width, a is span, and kb and k. are constants dependent upon beam loading.

Values of kb and k, for several loadings are given in table 12-1. If the sandwich panel is ~ported on all four ~~-fi.is.tiad . oftwo ends, tlie deflections and stresses are decreased. For a complete treatment of sandwich plates under loads nor- mal to the plane of the plate see the Bibli- ography at the end of this chapter. Th~ buckling load, per unit width, of a sand- wich panel with no edge members and loaded as a simply supported column is given by the formula: · (12-5) where N is . the buckling load per unit panei width, a is panel length, Dis flexural stiffness, U is shear stiffness, and n is number of half waves into which the panel buckles. A mini- ~is obtained for n =· 1 and this minimum is then This buckling form is often called "general buckling" and is illustrated in sketch A of The appearance of this buckling failure re- sembles a crimp as illustrated in sketch B of figure 12-4. "Shear instability" or "crimping" failure is always possible for edge-loaded sandwich and is a limit for general instability and not a localized failure. If the sandwich panel under edge load has edge members, inserts perhaps, the edge meJn- bers will carry a load proportional to their transformed area ( area multiplied by ratio of FACING- CORE I I I ~ l t A • GENER,~L BUCKL!

Edge members will also raise the overall panel buckling load be- cause of restraints at edges. Estimates of the effects of edge members can be obtained from Zahn and Chena-. If the edge members are rigid enough to provide simple support but do not clamp the panel edge, an increase in buck- ling load per unit panel width is obtained. For a sandwich of isotropic facings on an isotropic core, the buckling load for a panel with a length greater than ita width (loaded edge) is given by the formula: · Ner • ( r'D )1 b• 1 + b•U 4t.JD ~D for b2U ~ 1 (12-8) "'D Ner • U for b•U ~ 1 where N Ci' is buckling load per unit panel width and b is panel wjdth. More complete formulas including sandwich with both facings ortho- tropic, one facing isotropic and one orthotropic, and with orthotropic cores, are given by Kuenzi, Norris, and Jenkinson. Buc~ing criteria for flat rer'..angular sand- wich ·panels under loads othH than compres- sion haYe also been derived Details for panels in edgewise shear are giv,m by Knenzi, Erick- sen, and Zahn, and for panels in edgewise bend- ing and under combine.d loading· by Kimel. Buckling of ~andwkh wall~ of cylinders has been derived for axial com!)ression loading by Kimel and Stein end Mayers, for torsion load- ing by March and Ku~"1Zi, and for external pressure by Kuenzi, B-Jhannan, and Stevens. All are covered-in M-ili+,ary Handbook 23A. Buckling of sandwich components has been emphasized because bucklir.g causes complete failure, usually producing severe shear crimp- ing at the edges .,.,f the buckles. Another im=- portant factor fa the necessity that facing stresses be no more than allowable values at design loads. Facir,g stresses are obtained by dividing the load oy the facing area under load. (Thus for sandwich in compression, the facing stress f ·= ft.:. . ) L• In a strip of sandwich construction sub- jected to both bending moments and shear loads, the mean facing stresses are given by: (12-9) where /1,2 is the mean compression or tension stress in facing 1 or 2 ; t1,11 is the thickness of facing 1 or 2; and M is the bending moment per unit width of sandwich. The shear stress in the core is given by (12-10) where /e, is core shear stress and Sis applied shear load per unit width of sandwich. Localized · failure of sandwich must be avoided. Such failure is shown as dimpling of the facings in sketch C and as wrinkling of the facings in sketch D of figure 12-4. The stress at which dimpling of the facings into a honeycomb core begins is given approximately by the formula : (12-11) where fd is facing stress at beginning of dim- pling, E is facing modulus of elasticity, t is fac- ing thickness, and s is cell size of honeycomb core (radius of inscribed circle). Increase in dimpling stress can be attained by decreasing the cell size. Wrinkling of the sandwich facings can occur because of instability of the thin facing supported by a lightweight core which acts as the facing elastic foundation. Wrin- kling can occur because of poor facing-to-core bond, resulting in a separation of facing from the core (fig. 12-4, D). Increase in bond strength should produce wrinkling by core crushing. Thus a convenient rule of thumb is to require that the sandwich flatwise tensile strength (bond strength) is no less than flat- wise compressive core strength. Approximate wrinkling stress for a fairly flat facing (pre- cluding bond failure) is given by: 1 I --(EE G ) 113 11· -2 r r (12-12) where f,r is facing wrinkling stress, E,. is core modulus of elasticity in a direction perpendic- cular to facing, and Gr is core shear modulus. Localized failure is not accurately predictable and designs should be checked by ASTM tests of small specimens. Because sandwich constructions are com- posed of several materials, it is often of inter- 12-6 'i ' , ' < I I I r I ( (' ( l' r ~ ; ~·· ·~-~--~~..- . '.' -~{( ; ' · ~ to a~pt ·to Aesi,n a minimum weight of the construction for a particular compon- ent. Several components and a general analy- sis for stiffness are discussed by Kuenzi. For a sandwich with similar facings having a re- quired bending stiffness, D, the dimensions to produce the minimum weight sandwich are given by: 1,, • 2 (Dw)1 " Ewo t -~ 1,, 4w (12-18) where 1,, is distance between facing centroids, t is facing thickness, E is facing modulus of elasticity, w is facing density, and We is core density. The resulting construction will hav~ very thin facings on a very thick core and will be proportioned so that the total core weight is two-thirds the total sandwich weight minus bond weight. It may be a most impractical construction because the required exceedingly thin facings may not be available. Many detailed design procedures necessary for rapid design of 81!,ndwich components for aircraft are summarized in Military Handbook 23A. Although the design of aircraft sand- wich has many details not needed for other applications, the principles are broad and can be applied to components of structures other than aircraft. DIMENSIONAL STABILITY, DURABILITY, AND BOWING OF SANDWICH PANELS ' In a sandwich panel any dimensional moYe- ment of one facing with respect to the other due to changes in moisture content and tem- perature causes bowing of an unrestrained panel. Thus, although the use of dissimilar fac- ings is often desirable from an economic or dec- orative standpoint, the dimensional instability of the facings during panel manufacture or ex- posure may rule out possible benefits. If di- mensional change of both facings is equal, the length and width of the panel will increase or decrease but bowing will not result. The problem of dimensional stability h~ chiefly related to the facings, because the core does not have enough stiffness to cause bowing of the panel or .to cam;e it to remain flat. The magnitude of the bowing effect, howeYer, de- · pends on the thickness of the core. It is possible to calculate mathematically the bowing of a sanch,·ich construction if the pel'- cent expansion of each facing is known. The maximum deflection is gi\'en approximately by: (12-14) where k is the percent expansion of one facing as compared to the opposite facing; a, the length of the panel ; and h, the total sand- wich thickness. In conventional construction, vapor barriers are often installed to block migration of vapor to the cold side of a wall. Various methods have been tried or suggested for reducing vapor movement through sandwich panels, which causes a moisture differential with resultant bowing of the panels. These include bonding metal foil within the sandwich construction; blending aluminum flakes with the resin bond- ing adhesives; and using plastic vapor barriers between veneers, overlay papers, special fin- ishes, or metal or plastic facings. Because added cost is likely, some of these methods should not be resorted to unless need for them has Lew1 demonstrated. A large test unit simulating use of sand- wich panels in houses was constructed at the Forest Products Laboratory in 1947. The pan- els used, comprising various facings on paper honeycomb cores, were observed for bowing and general performance. The experimental assembly sho,\·n in figure 12-5 represents the type of construction used in the test unit. De- tails of obsen·ed beha\·ior of various sandwich panel constructions after exposure in the test unit for 20 years are giYen by Shenrnod. The major conclusions were that with proper com- binations of facings, core, and adhesfres, satis- factor:c,· sandwich panels can be assured by careful fabrication techniques. This was indi- cated by results of strength tests conducted on pant=:ls exposed for up to 20 years in the unit. THERMAL INSULATION OF SANDWICH PANELS Satisfactory thermal insulation can best be ohtainecl "·ith sancl,Yich panels by using cores having-lo\\· thermal conductivity, although the use of reflecti\'e layers on the facings is of some \·alue. Paper honeycomb cores h:n-e thermal conducti,·itr rnlues (k rnlues) ranging from 0.30 t0 0.65 British thermal units per hour per I° F. pe1· square foot per inch of thickness, ciepending on the particular core construction.

Honeycomb with open cells can a1ao have greater conduc-- tivity if cells are large enoµgh (larpr than about % inch) to allow convection currents to develop. An improvement in the insulation value can be realized by filling the honeycomb core with fill insulation or a foamed-in-place resin. FIRE RESISTANCE Of SANDWICH PANELS In tests at the Forest Products Laboratory, the fire resistance of wood-faced sandwich pan. els was appreciably higher than that of hol- low panels faced with the same thickness of plywood. Fire resistance was greatly in- creased when coatings that intumesce on ex- posure to heat were applied to the core mate- rial. The spread of fl.re through the honeycomb core depended to a large extent on the aline- ment of the flutes in the core. In panels having flutes perpendicular to the facings, only slight spread of flame occurred. In cores in which flutes were parallel to the length of the panel, the spread of flame occurred in the vertical di- rection along open channels. Resistance to flame spread could be improved by placing a barrier sheet at the top of the panel or at in- tervals in the panel height, or, if strength re- qui remen ts permit, by simply turning the length of the core blocks at 90° to the vertical direction. .
