ABSTRACT:
A manufacturing method for a composite fabric material is disclosed, which includes: holding a bundle of fibers under tension, the fiber being continuous filaments of carbon fibers, aramid fibers, or glass fibers, etc.; placing a layer of a matrix material over and under the fiber bundle, the matrix material being a thermoplastic adhesive material such as polyamide resins, thermoplastic polyurethane, or polyester, etc.; heating the matrix material to melt it and applying a pressure on the layers while the fiber bundle is under tension; and cooling the layers, whereby the fibers are locked in place by the adhesive. Composite material layers produced by the above steps may be laminated and further processed or formed as desired. The composite fabric materials manufactured by this method have superior tensile properties, compression properties, impact properties, and impact dispersion and propagation properties compared to composite fabric materials made with conventional methods.
