It is a carbon fiber reinforced polymer blended with titanium alloy, which has the high strength and toughness of titanium alloy, but also does not lose the characteristics of lightweight carbon fiber.
Each carbon fiber is made up of thousands of smaller pieces of carbon, about five to eight microns across, almost entirely of carbon. The earliest generation (such as T300, HTA and AS4) had a diameter of 16-22 microns. The newly developed carbon fiber (such as IM6 or IM600) is about 5 microns in diameter.
At the atomic level, carbon fiber is similar to graphite in that it consists of layers of carbon atoms arranged in a hexagonal pattern (graphene sheets). The difference is in the way the layers connect. Graphite is a crystalline structure with loose interlayer connections, whereas carbon fiber is not a crystalline structure and interlayer connections are irregular. This prevents slip and increases the strength of the material.
The general density of carbon fiber is 1750 kg/m. The specific heat capacity of carbon fiber is lower than that of copper. When heated, the carbon fiber becomes thicker and shorter. Although carbon fiber's natural color is black, it can be dyed in different colors.
