Simulation machining of fiber-reinforced composites: A review

Fiber-reinforced composites/fiber-reinforced polymer is excellent material owning the performance of high strength, high toughness, light weight, good fatigue resistance and shock absorption, and strong designability. It has a wide range of application prospects. The reinforcing fiber makes the cutting of the composites far from easy. When machining of FRP, the high tool wear, defects on machined surface, and poor processing efficiency severely restrict its wide application. Exploring the cutting mechanism of FRP has very important practical significance. In recent years, simulation technology based on discrete element and finite element methods has gradually been applied to the research field of material cutting. This paper summarizes the methods, theories, and conclusions in cutting simulation of fiber-reinforced composites in recent years, and finally puts forward the future focus and development direction of fiber reinforced composite cutting simulation research.
