During pultrusion, continuous fiberglass bundles, belts or cloth impregnated with resin glue are continuously produced with unlimited length fiberglass profiles under the action of traction. This process is suitable for producing FRP profiles with various cross-section shapes, such as bar, tube, I-shape, groove, square profile and hollow profile.
拉擠制品中，環氧樹脂體系固化劑一般采用酸酐類固化劑。盡管也采用不飽和樹脂拉擠成型加工，但其綜合性能，尤其在機械性能、絕緣性能、收縮率方面，均不如環氧樹脂拉擠產品。

Winding products are made by winding resin impregnated continuous fibers (cloth, pre impregnated yarn) onto the core mould according to certain rules, and then solidify and demould to obtain certain shape products.
纏繞制品更具代表性的是使用期長、粘度小、發熱量少、毒性小的環氧固化體系，故一般都選用液體酸酐為主。
The most representative of winding products is the epoxy curing system with long service life, small viscosity, less heat and less toxicity, so liquid anhydrides are generally selected as the main component.
5、 模塑料制品
5. Molded plastic products
