What is fiberglass pultrusion?
Glass matShort cut felt requirements: area quality is uniform; short cut raw silk and sticky C agent evenly distributed; moderate dry felt strength; good permeability. Used of products of less demanding strength.The continuous felt reinforced effect is shorter and the felt is good. Ibid.Surface mats play surface modification and acid resistance.Stitched felt does not contain adhesive, it has good penetration property and lower price.
RovingRoving has both plied yarn and direct yarn, with a linear density of 1100 (1200) to 4400 (4800). Requirements: good band composition, good unwinding property, uniform tension, uniform linear density and good permeability.
Glass fiber pultrusion: the reinforcement materials used in pultrusion are glass fiber and its products, such as roving, glass fiber felt and so on. In order to meet the special requirements of the products, aramid fiber, carbon fiber, ultra-high molecular weight polyethylene fiber and basalt fiber can be used.
