Thermoplastic Carbon Fibre Composites

Summary

The evolution of carbon fibre/thermoplastic (CF/TP) composites is being facilitated by the previous development of similar materials wherein glass fibres provided the reinforcement. CF/TP moulding compounds wherein many TP’s may serve as the matrix are shown to be a rapidly developing commercial material for use in applications which require electrical grounding, improved wear, and/or dimensional stability characteristics.

The status of development of continuous CF reinforced thermoplastic preforms and potential composite applications is also reviewed. Significantly increased damage tolerance by way of improved toughness of the matrix (in comparison to thermosets) is the principal driver for development of these materials. Shorter fabrication cycles, reduced scrap and infinite shelf-life at ambient conditions are also providing impetus. With the advent of advanced TP’s such as PEEK (polyether etherketone), PPS and polyamide-imides, their improved high temperature performance and solvent resistance are enabling serious development for aircraft) aero space applications. With the development of suitable product forms and fabrication technology, cost-effective applications of CF/TPs seem certain to evolve.
