Problems solved by technology

However, studies have shown that although acid-base etching treatment can effectively increase the surface area of ​​glass fibers and improve the wettability of glass fiber surfaces, the surface layer of glass fibers is destroyed after being etched by acid and alkali, resulting in stress concentration and a decrease in its own strength. dropped

Abstract

The invention discloses an improved glass fiber reinforced plastic material which comprises glass fiber textured yarns, epoxy resin, an epoxy resin reactive diluent, a tackifier, a plasticizer, a silane coupling agent, a curing agent and fillers. The composite material is good in interfacial property, high in strength, large in carrying capacity and good in impact resistance.

Description

technical field [0001] The invention relates to fiber-reinforced composite materials, in particular to an improved FRP material. Background technique [0002] FRP material is a material in which glass fiber reinforced materials are embedded in cured thermosetting resin or wrapped by it to form a composite structure. At present, most of the FRP materials used in the market are formed by resin-impregnated glass cloth materials. The method has a good wetting effect and the prepared glass fiber has a high content. However, due to the limitation of the volume and shape of the glass cloth, it is especially not suitable for products such as pipe joints, tee fittings, and elbow fittings, which are not easy to be uniformly compressed. In addition, the impact resistance of the FRP material prepared by this method is poor, and the laminated surface is prone to delamination. In order to solve the above problems, some researchers cut the glass fiber into glass fiber powder with a fibe...
