Advantages and disadvantages of pultrusion molding

Pultrusion molding is a special process in the molding process of composite materials, the advantages are: ① the production process is fully automated control, high production efficiency; ② pultrusion molding products in the fiber content can be as high as 80%, soaking in the tension of the glue, to give full play to the role of reinforcing materials, product strength; ③ products longitudinal and transverse strength can be adjusted to meet the mechanical properties of the products of the different The longitudinal and transverse strength of the products can be adjusted arbitrarily, which can meet the requirements of different mechanical properties of the products; ④ There is no edge waste in the production process, and the products do not need post-processing, so it saves labor, raw materials, and energy consumption compared with other processes; ⑤ The quality of the products is stable, and the reproducibility is good.

The disadvantage of the pultrusion molding process is that the product shape is monotonous, can only produce line-shaped profiles, and the transverse strength is not high.
