Problems solved by technology

However, this procedure has disadvantages: polycarbonate (PC) has a very high viscosity, and this impregnation step necessitates the use of low molecular weight, i.e. low viscosity PC, which deliberately has very poor suitability, e.g. Low resistance of stress crackers to polar solvents

Embodiment 1

[0521] Example 1: Production of Fiber Composite M

[0522] Acrylonitrile-styrene-maleic anhydride copolymer in the form of thermoplastic molding composition A (prepared from 75% by weight of styrene, 24% by weight of acrylonitrile and 1% by weight of maleic anhydride) based on 40% by weight of the fiber composite ) with 60% by weight, based on the fiber composite, of glass-based reinforcing fibers [GW 123-580K2 from P-D Glasseiden GmbH] having chemically reactive functional groups (silane groups) at the surface.

Embodiment 2

[0523] Example 2: Creation of Fiber Composite N

[0524] Acrylonitrile-butadiene-styrene copolymer in the form of thermoplastic molding composition A (composed of 45% by weight of butadiene, 30% by weight of styrene, 24% by weight of and 1% by weight of maleic anhydride) with 35% by weight of glass-based reinforcing fibers with chemically reactive functional groups (silane groups) at the surface based on fiber composites [GW 123-580K2 from P-D Glasseiden GmbH] For compounding. The fiber composite is then ribbed.

Abstract

The present invention relates to a fiber composite material W with increased translucency and / or mechanical strength, said fiber composite material W comprising a copolymer C comprising a monomer A-1, wherein A-1 is combined with The functional group B-1 on the surface of the fiber B embedded in the fiber composite W forms a covalent bond, and this fiber composite W has a higher ratio than a fiber composite in which the copolymer C does not contain A-1 W greater translucency and / or mechanical strength. The invention further comprises a method for producing a fiber composite material W with increased translucency and / or mechanical strength.

Description

technical field [0001] The present invention relates to a fiber composite material W having enhanced translucency and / or improved mechanical strength, said fiber composite material W comprising a copolymer C comprising monomers A-I, wherein A-I is composited with The functional group B-I on the surface of the fiber B in material W forms a covalent bond, and the fiber composite W exhibits a higher composite fiber than a corresponding fiber composite in which the copolymer C (or C') does not contain A-I (as a building block). The material W has higher translucency and / or improved mechanical strength. The present invention additionally encompasses a method of producing a fiber composite material W with enhanced translucency and / or improved mechanical strength. Background technique [0002] Fiber composites (fiber composite engineering materials, fiber reinforced composite (engineering) materials or "organosheets") consist of numerous reinforcing fibers embedded in a polymer ma...
