LONG-FIBER-REINFORCED POLYMER MATERIAL AND METHOD AND INSTALLATION FOR ITS MANUFACTURE
摘要:
The fiber-reinforced polymer material, in particular for processing in the injection molding and extrusion method, is composed of granular materials having integrated long-fiber reinforcement. The granular materials are designed as wound elements (5), which have continuous fiber strands (3) including continuous reinforcing fibers (1) impregnated with polymer material (2). The wound elements (5) contain more than one turn (6) of the impregnated continuous fiber strands (3), wherein the turns (6) at least partially overlap each other such that the turns are arranged over each other and/or next to each other. The wound elements (5) can be continuously produced by winding and solidifying the impregnated continuous fiber strands (3) around a winding axis (23) or on a winding core (22) and subsequently separating the wound elements from each other, in particular by means of a winding core moved in an oscillating (+x1, −x1) manner and using melted thermoplastic polymer material (2).
