Abstract
This granular composite is obtained by chopping granules from a composite strand which contains at least one bundle of gear crimped fibers embedded in a polymer. The fibers can have reinforcing or electrically conductive properties. The granular composite is mixed with another polymer granulate and softened, whereby the fibers are dispersed in the polymer mass, which is then shaped, for example, by injection molding into plastic articles.
Claims24
A composite strand for use in the manufacture of plastic articles, said strand comprising fibers embedded as a plurality of bundles in a polymer, wherein at least one of said bundles comprises crimped fibers, and wherein said crimped fibers in said at least one of said bundles possess an almost sinusoidal zigzag crimp with a wavelength W between 2 and 30 mm and an amplitude A between 0.2 and 7 mm and in which W/A is larger than 2.
