Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%. High temperature resistance ranks first among all chemical fibers. It is made of acrylic fiber and viscose fiber, which is oxidized and carbonized at high temperature. It is an excellent material for manufacturing aerospace and other high-tech equipment.
Carbon fiber is generally made of polyurethane resin and carbon fiber filaments. Carbon fiber is resistant to high temperatures, but the general resin matrix is not resistant to high temperatures. When processing carbon fiber plates, if there is high temperature, it will cause the basic softening. At this time, it is difficult to cut carbon fibers directly, which will cause a great loss to the cutting, so the temperature must be lowered when cutting carbon fiber plates. There is a special carbon fiber cloth cutting machine for carbon fiber cloth. There is no special tool for cutting carbon fiber boards, but the cutting methods of traditional materials are also applicable, such as mechanical cutting, water cutting, ultrasonic cutting, laser cutting, etc. can be used for carbon fiber boards .
Laser cutting
The choice of laser cutting carbon fiber speed is not only related to laser cutting parameters, but also related to the thickness of carbon fiber and the absorption rate of carbon fiber to laser. For laser cutting equipment with a certain power, the thicker the carbon fiber thickness, the cutting speed must be reduced in order to obtain good cutting quality when laser cutting carbon fiber, which also makes the time required for laser cutting carbon fiber longer, and the carbon fiber is likely to be overburned. Therefore, the quality is reduced; if one wants to improve the processing efficiency, it will inevitably lead to the problem of kerf and thermal influence due to the increase of energy absorbed by carbon fiber.
