Study On The Formation Mechanism of Cutting Surface of Carbon Fiber Reinforced Composites

Abstract: Carbon fiber-reinforced plastic (CFRP) is used widely in aerospace. The cutting mechanism of CFRP is markedly different from that of metals due to anisotropic and non-homogeneous material structure. The cutting mechanisms are highly dependent on the fiber orientation. The quality of the machined surface can be affected by the fiber fracture models. In this paper, based on the elastic foundation beam theory and the Hertzian contact theory, the cutting mechanics are established. And the cutting model is simulate… Show more

“…CFRP is widely used in aerospace, automobile industry, petroleum industry and ship industry because of its excellent heat resistance, low thermal expansion coefficient [1,2] and high specific strength. During the preparation and service process of CFRP laminates, due to the influence of manufacturing process, cyclic stress and impact damage, it is easy to form defects such as interlayer delamination, surface scratches, matrix cracks and debonding [3]. These defects seriously affect the performance of CFRP.…”
