Multiaxial structure, a process for the preparation of a fiber composite plastic and fibre-plastic composite

摘要

Multiaxial structure, comprising two or more layers (12; 112) of fiber strands (14; 114), wherein the fiber strands (14; 114) of each layer (12; 112) having the same orientation and the fiber strands (14; 114) of a first position (12a; 112a) have a different orientation than the fiber strands (14; 114) of a second position (12b; 112b), and wherein the fiber strands (14; 114) of the multiaxial structure (10; 110) reinforcing fibers (15; 115) comprise or consist of reinforcing fibers (115), characterized in that fiber strands (14; 114) by means of thermoplastic threads (20) are sewn together, the multiaxial structure (10; 110) with a thermoplastic matrix precursors component is provided, and the thermoplastic filaments (20) of the same material as the matrix precursors component, which is selected from polyether ether ketone (peek), polyether imide (pei), thermoplastic polyetherimide (tpi), polyphenylene sulfide (pps) and polyether ketone ketone (peek).
