ABSTRACT:
A high tenacity, high elongation, low shrinkage synthetic fiber is treated to enhance stiffness and interfilament coherency, then dusted with a release agent, resulting in a fiber, combined in multiple high denier bundles, which can be cut at high speed to suitable reinforcing lengths for use in reinforcing a resin matrix. The cut fiber can be used in bulk molding compounds (BMC), sheet molding compounds (TMC) and spray-up applications due to ease of cutting.
