Abstract
Today, composite materials and sandwich structures have been studied due to their unique properties such as strength to high weight, corrosion resistance, ability to absorb energy and sound. One of the most important applications of layered composites is their use in the construction of sandwich structures. Recently, sandwich panels have been widely used in engineering structures due to the mechanical properties they show in various fields such as bending behavior, shear, impact response and dynamic loads. Fatigue and quasi-static have been used. In this regard, this research has experimentally investigated the mechanical behavior of composite sandwich panel with multi-layer corrugated core subjected to quasi-static three-point bending. Parameters such as bending stiffness and maximum bending load tolerance for corrugated core geometries (square and trapezoidal) by changing the core from square to propeller and also the effect of adding polyurethane foam were studied. The purpose of adding corrugated composite inside the core is to strengthen it and, as a result, strengthen the sandwich structure against bending loads without significantly increasing the weight of the structure. Composite plates and corrugated cores are made by vacuum resin transfer technique and using E-glass woven fabric and ML506 epoxy resin with 15% hardener. The experimental results show that the multilayer composite sandwich panels strengthen the structure in the quasi-static three-point bending process. The main damage and failure mechanisms of sandwich panel samples during the load bearing process are: matrix cracking, fiber breakage, delamination, local indentation, global bending, crushing and buckling of cell walls and skins.
