Abstract

The invention relates to rectangular winding glass fiber reinforced plastic. The glass fiber reinforced plastic is sequentially provided with a glass fiber reinforced plastic lining layer, a glass fiber reinforced plastic winding layer and a glass fiber reinforced plastic outer protective layer from inside to outside; wherein the glass fiber reinforced plastic lining layer comprises a gridding cloth layer, and a glass fiber surface felt layer, and is formed in a soaking and boding manner through a linking slurry material; the glass fiber reinforced plastic winding layer is formed by combininga plurality of winding layers and alkali-free cloth in an up-down staggered mode at intervals; the glass fiber reinforced plastic outer protective layer comprises glass steel wire cloth, and the polyester surface felt layer is formed by soaking and bonding protective slurry. The winding layer is formed by weaving and winding long-cut glass fibers soaked by toughening slurry, short-cut glass fiberssoaked by reinforcing slurry and coarse gauze soaked by reinforcing slurry; the alkali-free cloth is alkali-free cloth soaked by the reinforced slurry. The invention discloses rectangular winding glass fiber reinforced plastic, which is manufactured by adopting a continuous winding process technology and has high interlayer bonding strength, so that the overall strength and rigidity of a glass fiber reinforced plastic pipe are stronger.

Description

technical field [0001] The invention relates to a rectangular winding glass fiber reinforced plastic, which belongs to the field of glass fiber reinforced plastic production. Background technique [0002] With the properties of light weight, high strength, corrosion resistance, long life, weather resistance, flame retardancy and high temperature resistance, FRP materials have been widely used. However, the FRP produced in the prior art has low rigidity, large deformation, and high requirements for construction. In order to improve the rigidity of FRP pipes, it is necessary to increase the amount of resin in FRP, which will cause the production cost of FRP to be too high, which is not conducive to the production of FRP. The existing technology also increases the performance of FRP by adding a coating on the outside of FRP. In the prior art, when producing rectangular FRP pipes, the hand lay-up process is used. This process has low efficiency, unattractive appearance, uneven ...
