Fiber Composite Material and Method for Production Thereof

Abstract

A fiber composite material includes fibers and a resin connecting the fibers. The composite material has a high strength while reducing resin consumption and has great flexibility with respect to subsequent deformation. To achieve this, threads are used that include a plurality of individual filaments and a resin which can be crosslinked under an impact of at least one physical variable and/or one chemical substance. The resin is provided in non-crosslinked condition, but is essentially solvent-free, and holds the individual filaments in the threads together, wherein the individual filaments are arranged unidirectional to each other, and the threads form a composite by bonding together at contact surfaces of their respective external enveloping surfaces through resin bridges. The invention further relates to a fiber composite material including resin in a crosslinked state as well as a method for producing the fiber composite material.

What is claimed is: 
     
         1 .- 12 . (canceled) 
     
     
         13 . A method for producing a fiber composite material including fibers and a resin connecting the fibers, comprising the steps:
 forming threads which respectively include a plurality of individual fibers that are held together through a resin that is crosslinkable under an impact of at least one physical variable or chemical substance, wherein the individual fibers of a thread are arranged unidirectionally and parallel to a longitudinal axis of the thread without a twist of the individual fibers relative to one another, and wherein the individual fibers of the thread are movable relative to one another;   weaving or knitting a fiber composite material from the threads so that contacting threads are connected with one another at contact surfaces of their outer enveloping surfaces through bridges of the resin provided in non-crosslinked condition, wherein the resin forming the bridges previously formed a portion of the threads;   compressing the fiber composite material so that the threads are pressed into one another at their contact surfaces;   placing the compressed fiber composite material into a mold; and   crosslinking the fiber composite material in the mold to provide the fiber composite material with its final strength.   
     
     
         14 . The method according to  claim 13 , comprising the step compressing the fiber composite material further during crosslinking in the mold.
