Technical Field

[0001] The invention relates to the technical field of cutting, in particular to a cutting device for carbon fiber prepreg. Background Art

[0002] Carbon fiber is a fiber material with a carbon content of more than 90%. It is a polymer fiber material made by treating carbon-containing raw materials under specific conditions with high temperature carbonization. Carbon fiber prepreg is an advanced composite material, which is made of carbon fiber tow and resin pre-treated by a specific process. In this process, the resin is evenly impregnated into the carbon fiber yarn, and then cured by heat treatment and cooling to form a semi-cured material with a certain viscosity and plasticity. This material combines the high strength and light weight characteristics of carbon fiber with the bonding properties of resin. It is widely used in aerospace, automobiles, sports equipment, construction and military fields. Carbon fiber prepreg is usually supplied in roll form and can be cut and formed according to the requirements of the final product.

[0003] In the process of cutting carbon fiber prepreg, due to the nature of the carbon fiber material itself, the prepreg is easily damaged during cutting, especially under fast and strong cutting operations. For example, when the pressure of the tool is too large, the cutting speed is too fast or the tool vibrates, the carbon fiber material may suddenly break, affecting the cutting accuracy and quality and causing damage to the carbon fiber prepreg. Therefore, a cutting device for carbon fiber prepreg is proposed, which is used to cut the carbon fiber prepreg continuously and at a uniform speed, avoiding the problem that the carbon fiber prepreg may suddenly break when the tool pressure is too large or the cutting speed is too fast.
