摘要：
The dimensionally stable composite material consists of a double fabric with spacer filaments. On both sides of the double fabric there is a plastics layers. Face and back fabric of the double fabric are linked with each other by means of incorporated rigid filaments which prevent the double fabric to be squeezed. The exterior plastics layers are curable laminates. FIG. 1 shows such a composite material.The material is obtained by applying fiber mats impregnated with curable synthetic resins to both sides of the double fabric containing spacer filaments, and subsequently bonding fiber mats and double fabric by compression.
