How carbon fiber products are machined

Compared with other materials, carbon fiber materials have the advantages of being light and thin, and can be used to make products of various complex shapes without special processing. Carbon fiber products are made of carbon fiber prepreg laminated and hot-pressed. After molding, the hardness and brittleness are relatively high, which leads to the need to pay attention to the later machining of them to prevent delamination and tearing. Follow Boshi Carbon Fiber to see how machining works.

When carbon fiber products are machined, delamination and tearing are prone to occur, which will lead to a decline in the performance of carbon fiber products. Due to the relatively high strength of carbon fiber products, the cutting force is higher, especially when processing carbon fiber products with thicker walls. . At this time, there will be a lot of heat around the hole, so it is recommended to choose a carbide or diamond drill when machining. Traditional twist drills are easy to cause debris accumulation. It is recommended to choose a drill with a center through hole and a cutting groove on the end face. This facilitates the discharge of debris.

When drilling carbon fiber products, the shear stress of the cutter head along the linear speed direction makes the surface layer of the carbon fiber material form a force to tear and delaminate without being bound, but as the drill bit goes deeper and deeper, the drill bit will A certain taper is generated, and then there is a force perpendicular to the surface of the carbon fiber product, which can resist the force of tearing and delamination, which can ensure the overall mechanical properties of the carbon fiber product.

When drilling to the bottom fiber layer, the bearing capacity of the bottom is relatively low, and wrinkles and burrs are prone to appear under the action of the axial direction. Therefore, in the process of correction, it is necessary to make the drill bit play the effect of trimming to ensure that the accuracy requirements of the holes meet the actual requirements.
