Abstract

Two kinds of woven spacer fabrics were designed and woven with high strength low extension technical polyester filaments. Then the sandwich composite panels were built by filling polyurethane foam in the space of the fabric and combined the epoxy resin on the surface of the fabric by means of handle paste shaping craft. Finally the property of the composites,including the flexure, impact resistance and compression performance, were measured. The experimental results showed that the woven spacer fabric sandwich panels have high flexibility and rupture toughness. When the stesses of bending, impact and compression were relieved, No visible distroy of the integral panel structure was observed.
