Abstract

The invention relates to filled polyamide molding materials containing glass fibers having a non-circular cross-sectional area in addition to a selected polymer mixture of polyamides and a flame retardant. The invention further relates to the use of such molding materials for producing molded articles as well as said molded articles.

Description

technical field [0001] The present invention relates to a filled polyamide molding compound which, in addition to a selected polymer mixture containing polyamide and a flame retardant, also contains long glass fibers with a non-circular cross-section. Furthermore, the invention relates to the use of such molding materials for the production of moldings and the moldings themselves. Background technique [0002] Currently, polyamides are widely used as structural components both indoors and outdoors, mainly due to their excellent mechanical properties. [0003] In particular, mechanical properties such as strength and stiffness can be improved by adding fiber reinforcement materials, such as glass fibers. [0004] Thus, EP 0 246 620 B1 describes a glass-fibre-reinforced thermoplastic in which cut sections of glass fibers are used which are rectangular, oval or flat in cross-sectional shape. [0005] In EP 0376616 B1 is disclosed a thermoplastic polymer composition comprising...
