Research on Drilling of Carbon Fiber Board
Carbon fiber composite materials have the advantages of light weight, high strength, impact resistance, corrosion resistance, and low thermal expansion coefficient, and become one of the four major aviation structural materials after aluminum, steel, and titanium. The carbon fiber board made of it needs to be drilled and connected during actual use. However, due to the brittleness of carbon fiber composite materials, delamination and tearing will occur under the action of cutting force.
