A lightweight sandwich composite consisting of thin E-glass/polyester skins bonded to a rigid PVC foam core (Divinycell H80), manufactured via vacuum-assisted resin transfer molding (VARTM) at room temperature. This class of material combines the corrosion resistance and workability of polyester/vinylester matrices with the structural efficiency of closed-cell foam, creating a high strength-to-weight panel suitable for marine and aerospace environments. Engineers select this sandwich construction when bending stiffness and impact resistance are critical but weight must be minimized, making it a practical alternative to solid laminates or heavier structural foams in cost-sensitive applications.
