Pultrusion process is mainly used to produce composite products. It is the most widely used technology in composite materials industry. With the environmental problems becoming more and more prominent in recent years,More and more attention has been paid to the fabrication of continuous fiber reinforced thermoplastic composites by pultrusion. Although thermoplastic pultrusion has a strong flexibility and resistance to strike, good resist...

Pultrusion process is still in the high-speed development stage. From the domestic and foreign development trend, mainly for the production of large size and complex surface, I hope the product, focusing on the development of new marine composite materials, power transmission, civil engineering structure, and high-rise building project. At present most thick pultruded products has reached 101.6mm, while the pultrusion process from the mo...

abstract This paper introduces and reviews the present situation and the latest progress of the production of mandrel for composite insulators, as well as the technological principle and product features of traditional pultrusion, vacuum assisted pultrusion and injection and pultrusion. Compared with the traditional process, the vacuum assisted pultrusion process has improved the transparency and stability of the products, while the inje...
