Abstract

The invention relates to an FRP pipeline which is characterized by comprising three layers of structures, namely a corrosion-resistant surface layer, an erosion-resistant intermediate layer and a strengthening outer layer, wherein the corrosion-resistant surface layer is an inner surface of the FRP pipeline; the corrosion-resistant surface layer is formed by curing glass fiber mats containing vinyl ester resin, and the proportion of glass fiber to resin is 10: 90; the erosion-resistant intermediate layer is formed by curing glass fiber chopped strand mats containing vinyl ester resin, and the proportion of glass fiber to resin is (25-35): (65-75); the strengthening outer layer is formed by curing the glass fiber chopped strand mats containing vinyl ester resin and glass fiber mesh cloth alternating lamination layers, and the proportion of glass fiber to resin is (30-40): (60-70).

Description

technical field [0001] The invention relates to an FRP pipeline and a manufacturing process. Background technique [0002] FRP, also known as glass fiber reinforced plastic or fiberglass reinforced plastic, is a composite material made of high molecular weight epoxy resin as a matrix, glass fiber reinforced plastic or carbon fiber as a reinforcement, and made through a composite process. The advantages include lightness, corrosion resistance, anti-aging, and insulation, so it is used to manufacture casings and printed circuit boards of various sports equipment, pipes, shipbuilding, automobiles, and electronic products. [0003] At present, compared with developed countries such as Japan, domestic FRP pipelines cannot avoid bubbles, pores, surface unevenness and other undesirable phenomena during production, which affect the quality of the pipeline and reduce the life of the pipeline. Contents of the invention [0004] The present invention provides a kind of FRP pipeline ...
