Abstract
A method for producing fibril-exhibiting high-performance fibers comprising the steps a) providing an organic, high-performance filament yarn having a breaking tenacity of at least 10 g/dtex and a modulus of elasticity in extension of at least 150 g/dtex, b) fibrillation of the high-performance filament yarn in a dry yarn state, through which a fibril-exhibiting high-performance filament yarn results, and c) cutting the fibril-exhibiting high-performance filament yarn resulting from step b) into fibril-exhibiting high-performance chopped fibers of substantially the same length, fibril-exhibiting high-performance chopped fibers of substantially the same length, an article comprising said fibers and one or more fillers, and a method for producing such an article are presented.
