Carbon-carbon composites are manufactured from continuous carbon fibres which are woven in a two or three dimensional pattern. The fibres are then impregnated with a polymeric resin. After the component has been shaped and cured the matrix is pyrolysed by heating in an inert atmosphere. This converts the matrix to carbon chain molecules which are densified by further heat treatments. The resulting composite consists of the original carbon fibres in a carbon matrix. Carbon-carbon composites have low density, high strength and high modulus. These properties are retained to temperatures above 2000ºC. Creep resistance and toughness are also high, and the high thermal conductivity and low thermal expansion coefficient provide thermal shock resistance. The woven structure of this composite can be seen in the low magnification micrograph. At high magnification, the fibres can be resolved. The fibres are continuous, but appear to be discontinuous as they are not parallel to the section plane of the sample.

Processing

Woven, continuous carbon fibres, impregnated with a polymeric resin. Composite is then shaped, cured, and matrix is pyrolised by heat in an inert atmosphere

Applications

Typical applications include braking materials in aircraft and high performance cars, ablative shields for aerospace vehicles such as the nose cap and wing leading edges of the Space Shuttle orbiter and hot-pressing moulds. A SiC coating is used to protect the composite from high temperature oxidation.

Composite Doors - The Advantage by Frank Colon

Composite Doors - The Benefits

Composite doors are a best addition to any house. The composite doors are affordable. Composite doors have a price that is around the middle of this market. Although not the cheapest, their quality and lifespan surpass the lower doors, supplying a far best value for money. The door surface is sturdy and thoroughly resistant to dents or cracks. The multi-point lock keeps the door securely in the frame at several points along the span, making it difficult to break-in.
