Carbon Matrix Composites
Carbon-carbon composites demonstrate
- High strength, light weight material
- High thermal conductivity and resistance to thermal shock
- Maintains its strength at temperatures around 2000ºC in inert atmospheres
- Must be protected from oxidation in air at high temperature
Thermax®* is used in the making of C-C Composites
- Thermax®* is added to the resin used to make the prepreg
- Thermax®* is used as thermal insulation in the furnaces used for chemical vapour deposition and for graphitising
Thermax®* in Prepregs
Resin used to make prepreg is ultimately converted to carbon to form the matrix. Typical thermosetting prepreg resins are 50-60 percent carbon. By adding Thermax®* to the resin before the impregnation process enables more carbon to be deposited during initial carbonisation. This reduces the time and cost of the densification process.
Chemical purity is extremely important in some C-C composite applications. In such instances the Thermax®* Ultra-Pure Grades are recommended.
Thermax®* is much easier to disperse in resin than other blacks of high purity, specifically acetylene black and channel black.
