Patent ID: 8409486

Claim:
A method for making structural parts with reinforcement fibers embedded in a matrix material consisting of a cross-linkable resin system, comprising the steps: a) providing the reinforcement fibers and a thermoplastic fiber material; b) securing the reinforcement fibers with the thermoplastic fiber material in a defined geometrical arrangement to form a preform, wherein the thermoplastic fiber material is spun from a raw material containing polyhydroxyether as a single polymer, and wherein the polyhydroxyether has an essential amorphous structure, a molecular weight Mw of 10,000 to 80,000 Dalton, and a glass transition temperature Tg of no more than 100° C.; c) embedding the reinforcement fibers and the thermoplastic fiber material in the matrix material by injection of the matrix material into the preform; and d) hardening the cross-linkable resin system, causing the thermoplastic fiber material to dissolve in the matrix material.
