Abstract
This study describes a new method for the preparation of composite materials using polyvinyl chloride (PVC) films and polyurethane (PU) foam elastomers. This new preparation method was applied to composite materials used for sound and thermal insulation in the automotive and aerospace industries, and it was found to be effective in reducing debonding and fracture defects. This feature was achieved via the formation of through-holes in the surface material and the substrate prior to lamination, which led to the increase in the flow of air and adhesive and allowed for better compatibility between the material layers. The composite material shows a tensile strength of up to 37.6 Kg⋅cm−2 and can achieve a tensile fracture strength of up to 281.3 N, if woven or biomaterials are used. This can be useful in solving challenges in the aerospace and automotive industries and may also act as a potential coating material for other applications in the future.
