Recent work on the cost-effective manufacturing of an extrusion-compression molded, long-fiber thermoplastic LFT XM-1002 tailcone for training rounds of military ammunition is compiled in this technical report. During the last decade, the engineering community has expanded the use of thermoplastic composites due to their inherent advantages over traditional thermoset composites including high toughness, inexpensive resin systems, short processing cycle times, recycling potential, excellent environmental resistance, and damage tolerance. Thermoplastic composites have a wide range of applications in the automotive and transportation industry for replacement of heavy metal components andor structures. LFT composites are a family of compounds with reinforcing fiber strands fiber lengths typically range from 6 to 24 mm combined with a thermoplastic matrix which can be any commodity or engineering thermoplastic polymer. LFTs have the ability to be molded into complex geometries featuring ribs, knock-outs, and thickness variations within the parts. LFT partscomponents can be processed by extrusion-compression, injection-compression, andor injection-molding processes.
