Carbon-Carbon Composites
Carbon reinforced with carbon, built for the extremes. C/C composites hold their strength above 2,000 C in inert atmospheres, which is why they sit inside rocket nozzles and aircraft brakes where almost nothing else survives.
What is carbon-carbon composites
Carbon-carbon composites, often written C/C, place carbon fibre reinforcement inside a carbon matrix. They are built up by repeated densification, either chemical vapour infiltration or impregnation with resin or pitch followed by pyrolysis, until the pores are filled and the matrix is dense. The result keeps its strength above 2,000 C in inert atmospheres, has low density, outstanding thermal shock resistance and very low thermal expansion.
