Carbon-carbon composites: a summary of recent developments and applications

Abstract

Carbon Fibre Reinforced Carbon (CFRC), or Carbon-carbon, is a unique composite material consisting of carbon fibres embedded in a carbonaceous matrix. Originally developed for aerospace applications, its low density, high thermal conductivity and excellent mechanical properties at elevated temperatures make it an ideal material for aircraft brakes, rocket nozzles and re-entry nose tips. It withstands temperatures in excess of 2000°C without major deformation. The properties are very much dependent on the manufacturing methods used for production. Although the general production technology is known, the combination of processes to achieve specially tailored properties remains the expertise of particular manufacturers. This paper reviews major developments of Carbon-carbon composites and describes actual and future applications. Improved oxidation resistance and continuously decreasing manufacturing costs make this family of materials more and more attractive to high performance applications as well as for general engineering design.
