Thermoplastic Composites


Greene Tweed’s thermoplastic composites provide solutions for aggressive and demanding applications. Through the use of novel fiber forms and matrix combinations, our composites service a wide variety of markets and needs. Whether in need of wear performance, part consolidation, mechanical strength, or environmental and chemical resistance, Greene Tweed’s material portfolio is fully characterized and backed by an experienced design, analysis, and manufacturing engineering team.

Greene Tweed specializes in the design and manufacture of components composed of high-performance thermoplastic matrices, with a focus on PEEK, PEI, PEKK, PFA, PTFE, and PA. These matrices, combined with short, discontinuous, braided, woven, and unidirectional fibers of both glass and carbon variations, enable tools for next-generation technology demands.
