Description

technical field [0001] The invention belongs to the technical field of carbon-carbon composite material production, in particular to carbon-carbon composite material production equipment and a production process thereof. Background technique [0002] Carbon-carbon composites are carbon matrix composites reinforced by carbon fibers and their fabrics. It has the advantages of low density, high strength, high specific modulus, high thermal conductivity, low expansion coefficient, good friction performance, good thermal shock resistance, and high dimensional stability. It is one of the few candidate materials used above 1650 °C today. The highest theoretical temperature is as high as 2600°C, so it is considered to be one of the most promising high-temperature materials, and has broad prospects because of its excellent characteristics. In the production engineering of carbon-carbon composite materials, it is necessary to add molten coal tar pitch to the raw materials for mixing....

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in the carbon-carbon composite material production equipment and its production process, in the process of adding molten coal tar pitch for mixing, when the molten coal tar pitch is mixed into the raw material, the mixing efficiency is low, and at the same time, Due to the viscosity of molten coal tar pitch, the device is prone to clogging when discharging, which affects the discharging efficiency of the device
