PROCESSING CHARACTERIZATION OF CONTINUOUS FIBER REINFORCEMENTS CO-MOLDED WITH LONG FIBER REINFORCED THERMOPLASTICS

摘要

An important advantage when designing with plastics is the ability to incorporate ribs and bosses directly into the part. Rib or grid stiffened polymer matrix composites are widely used in aerospace, automobile and civil infrastructure applications in recent years due to their high impact and fatigue resistance, high strength and stiffness to weight ratios and damage tolerance. However, processing complexity increases when fiber filled polymer has to fill ribs and small cavities. An innovative method of incorporating ribbed features in molded parts is using unidirectional tapes that are co-molded with a skin. This work focuses on co-molded Long Fiber Thermoplastics (LFTs) with pre-consolidated (pultruded/compression molded) sections of continuous reinforced thermoplastics tapes.
