Effect of Faces Type and Thickness on Mechanical Properties of Sandwich Panels

Sandwich panels are new kind of layered composites that usually are composed of three layers and their core layers thickness is higher but the top layers are determinative indetermination of the products strength and stiffness. In this study, effect of faces type and thickness on mechanical properti...

description Sandwich panels are new kind of layered composites that usually are composed of three layers and their core layers thickness is higher but the top layers are determinative indetermination of the products strength and stiffness. In this study, effect of faces type and thickness on mechanical properties of sandwich panels was investigated. The variables included, faces type with 3, 4 and 5 mm thickness (beech face, popular face) and adhesive type (PMDI). After making panels, sampling test (based on DIN- EN 326-1) was considered. Mechanical properties of panels included modulus of elasticity as well as module of rupture (based on DIN- EN 310 standard) and impact bending strength (IBS) (based on ASTM- D 3499 standard) were measured. The gathered data were analyzed as completely randomized factorial design. The results showed that, the thickness of faces has a significant effect on the mechanical properties. With increasing thickness of 3 to 5 mm, modulus of rupture, modulus of elasticity and impact bending strength (IBS) increased. The interaction effect between species and thickness showed that using of beech genus with 5 mm thickness leads to increase of mechanical properties in sandwich panels.
