Deformable mat comprising a fibrous reinforcement for the production of composite materials which have a thermoplastic matrix

摘要

Deformable mat (14, 45), in particular for the production of mold parts, consisting of at least one nonwoven fabric (10, 22), comprising:at least one reinforcing material andat least one thermoplastic material,the materials are located in the form of at least one continuous yarn and / or at least of a chopped yarn before, wherein the yarns (1) is completely or partially of fibers of a reinforcement material and fibers of a thermoplastic material, and the yarns (1) at least fifty percent by weight or preferably at least eighty percent by weight of mixed yarns include,the yarns (1) are interconnected in such a manner that the mat (14, 45) in each direction, an elongation at break of at least fifty percent, preferably of one hundred to one hundred fifty percent, respectively, wherein the mat (14, 45) a porosity in a range of sixty-five percent has to eighty percent.
