Efficient and Flexible Technology for Binder Roving Manufacturing

Jens Mack, Peter Mitschang


Liquid Composite Molding (LCM) processes are state of the art for the manufacturing of Fiber Reinforced Polymer Composites (FRPC). In the present paper a newly developed method for the manufacturing of binder rovings is defined. The binder roving consists of heavy tow carbon fibers combined with thermoset binder material. Different manufacturing units, such as the binder conveying system or the binder application system, were developed and optimized regarding the distribution quality and the output rate. For all tests a 50k SGL roving and a Huntsman XB 3366 binder material were used as input material.
