Processing, structure and properties of pitch-based carbon-carbon composites
- Univ. of Leeds (United Kingdom)
The potential of carbon-carbon (CC) composites as materials for high temperature applications was recognized at a very early stage, leading to their development in the 1960`s as materials for thermal protection during space vehicle re-entry. By the early 1970`s, two basic approaches to the formation of the carbon matrix were established, namely through chemical vapor deposition from a hydrocarbon gas (CVD) and through carbonization of a carbon-bearing resin or pitch. Fundamentally, little has changed since those early years with respect to these basic methods of CC composite fabrication. Further developments have, however, involved the introduction of multidirectional fibre architectures in order to reduce the mechanical anisotropy present in unidirectionally and bidirectionally reinforced composites caused by poor mechanical properties in the unreinforced directions. The strategic importance of several aerospace applications of CC composites, including military rocket nozzles and nose cones, the NASA space shuttle nose cone and leading edge protection surfaces, aircraft brake discs and gas diverter fins, ensured their continued development during the 1970`s and 1980`s.
