Carbon fibre-reinforced carbon (aka carbon–carbon‚ abbreviated C/C) is a composite material consisting of carbon fibre reinforcement in a matrix of graphite. It was developed for the nose cones of intercontinental ballistic missiles‚ and is most widely known as the material for the nose cone and wing leading edges of the Space Shuttle orbiter. It has been used in the brake systems of Formula One racing cars since 1976; carbon–carbon brake discs and pads are a standard component of Formula One brake

of standard AA1199-O4‚ with minor deviations. The deviations could be attributed to the processing conditions and/or purity level. To have a justified comparison‚ the processing conditions were kept same for the fabrication of Al-CNT composites. In Al-CNT composites’ specimens‚ the yield and tensile strengths increased from 29 MPa and 56 MPa to 97 MPa and 109 MPa‚ respectively. However‚ a decrease in elongation from 22.6 % to 7.4 % was observed. It is believed that the amelioration of mechanical

A composite is defined as the combination of two or more chemically different materials that have properties better than when the compounds act alone. Resin composites‚ which are used in dentistry‚ are compounds composed of three separate agents that act together to form a rigid polymer. The three agents that act together to form the polymer include‚ an organic resin matrix‚ inorganic filler‚ and a coupling agent. The most important agent‚ the organic resin matrix‚ is typically composed of a compound
