Abstract

The pull and compression process comprises intensifying material arrangement, soaking the resin glue, performing, filling into stripping material, compressing plastics to solidify, extraction, cutting and final product. Filled with stripping material, product can have even rough surface, for the benefit of bonding of it with other materials, stable in product dimension, strict quality control, standardization with simplified process and reduced cost. It mainly uses in structural strength supplementing for all kinds of fiber intensifying plastics, distributing electric insulation core and other fields.

Description

technical field

[0001] The invention relates to the field of composite material profile production, in particular to a new pultrusion process and its products. Background technique

[0002] FRP is scientifically known as fiber reinforced plastic, and it is customarily called glass fiber reinforced plastic in China. It is a composite material composed of synthetic resin as a matrix material, fiber and its products, among which glass fiber is the most commonly used reinforcing material. Since FRP came out, after decades of exploration and hard work, FRP molding processes include hand lay-up, winding, pultrusion, centrifugal casting, GMT and many other methods.

[0003] The pultrusion process is a method of continuous production of composite material profiles. It impregnates untwisted glass fiber rovings on the creel and other continuous reinforcing material mats, surface mats, etc. with resin, and then passes through a molding die that maintains a certain cross-sectional shape...
