Description
Technical Field
The invention belongs to the technical field of composite material cutting processing, and particularly relates to a mechanical processing method for a sharp corner structure of a glass fiber reinforced plastic part.
Background
Glass Fiber Reinforced Plastics (FRP), also known as GFRP, fiber reinforced plastics, generally refer to unsaturated polyester, epoxy and phenolic resin matrices reinforced with glass fibers. The reinforced plastic using glass fiber or its product as reinforcing material is called glass fiber reinforced plastic or glass fiber reinforced plastic, and is different from toughened glass.
Because of the variety of the resin used, there are polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic glass fiber reinforced plastics. Light weight, hardness, non-conductivity, stable performance, high mechanical strength, less recovery and corrosion resistance. Can replace steel to manufacture machine parts, automobile shells, ship shells and the like.
The glass fiber Reinforced plastic is known as Fiber Reinforced Plastic (FRP), i.e., fiber Reinforced composite plastic. The fiber is classified into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, and the like according to the difference of the adopted fiber. It is a composite material using glass fibre and its products (glass cloth, band, felt and yarn, etc.) as reinforcing material and synthetic resin as base material. The fiber reinforced composite material is composed of reinforcing fibers and a matrix. The diameter of the fiber (or whisker) is very small, generally below 10 mu m, the defects are few and small, the fracture strain is about thirty thousandths of a thousand, and the fiber (or whisker) is a brittle material and is easily damaged, fractured and corroded. The matrix is a tough material with much lower strength and modulus than the fiber, can bear large strain, and often has viscoelasticity and elastoplasticity
In the aviation field, since airplanes have extremely high requirements for weight and strength, glass fiber reinforced plastic materials are often used in airplane processing due to their characteristics such as light weight and high strength.
