Abstract
Fiber length attrition occurs in all the elementary step of processing during the injection molding of long fiber reinforced thermoplastics containing pultruded pellets. When fiber length attrition is kept to a minimum, there is considerable improvement in the mechanical properties, especially impact strength. Specifically, the state of fibers was examined at the end of pultruded pellet compaction and conveying in the feed and transition zones, during and at the end of melting, mixing and pumping occurring in the transition and metering zones as well as at the nozzle, runner, gate and molded part regions.
