Carbon-carbon bolts, also known as C/C screws and carbon-carbon bolts, are products obtained from carbon-carbon composite materials after precision machining by CNC machining centers. Manager Xu of Liugong said that they were widely used in industrial production at the beginning. It is a graphite screw. Graphite has strong temperature resistance, with a melting point of 3850 degrees and a boiling point of 4200 degrees, so it is widely used in many high-temperature industries. However, due to the high density of graphite, there are disadvantages in some use environments that pursue lightweight. Subsequently, Liugong developed products made of carbon-carbon composite materials, such as carbon-carbon screws, carbon-carbon plates, carbon-carbon thermal fields, and so on.

Carbon-carbon composite material is a full-carbon composite material made of carbon fiber and its fabric as a reinforcing material and carbon as a matrix through processing and carbonization. The carbon-carbon composite material has a carbon element content of more than 99% after high temperature heat treatment, so the material has a series of excellent properties such as low density, high temperature resistance, corrosion resistance, good thermal shock performance, acid, alkali, salt, friction and wear resistance. In addition, the room temperature strength of carbon-carbon composites can be maintained to 2500 °C, which is insensitive to thermal stress and has good ablation resistance. Therefore, the hexagonal carbon-carbon composite material has excellent mechanical properties, which can not only bear heavy loads as a structural material, but also play a role as a functional material, and is suitable for various high-temperature applications.

The following Liugong Graphite Manager Xu briefly introduces the characteristics of carbon-carbon composite materials, the raw material of carbon-carbon screws:

(1) Physical properties: The chemical composition of C/C composites after high temperature heat treatment, carbon element is higher than 99%, low density, has strong affinity, due to the high melting point of carbon element, it has high temperature resistance, corrosion resistance and thermal shock performance Good properties, acid, alkali, salt resistance.

(2) Mechanical properties: The strength and elastic modulus reflect the mechanical properties of C/C composites, and the friction and wear resistance is good.

(3) High temperature stability: The room temperature strength of the C/C composite material can be maintained to 2500 ℃, which is insensitive to thermal stress and has good ablation resistance.

(4) Comprehensive performance evaluation: C/C composite materials have good strength and elastic modulus at room temperature, and there are few steps in the production of C/C composite materials, which can save materials and manufacturing costs, and have high safety and reliability.

Liugong LG-10201 grade C/C composite material is made of polyacrylonitrile-based carbon fiber through a special process of compounding, curing, deposition and purification. It has high strength, high rigidity, high density, small expansion, and high temperature resistance. , corrosion resistance, friction resistance, thermal shock resistance and other characteristics, especially suitable for high temperature structural parts such as heating elements, fasteners, transmission parts, support trays, etc. under vacuum high temperature conditions.

The main application fields of Liugong LG-10201 grade carbon-carbon composite materials:
