Pultrusion technology, pultrusion molding can continuously produce fixed-section fiber-reinforced, weight-reduced composite materials, which greatly improves the molding efficiency and is suitable for mass production; in addition, the production process can be fully automated and controlled, and the product cross-section shape can be realized Serialization and standardization have significantly reduced the dispersion of the quality of composite products and have stable performance; the fiber content is high, and since the fibers are fully straightened under tension during molding, the fiber properties can be fully exerted and the longitudinal mechanical properties are outstanding.
