Description

technical field [0001] The invention relates to the technical field of FRP preparation, in particular to a high-strength FRP. Background technique [0002] FRP, that is, fiber-reinforced plastics, generally refers to reinforced plastics that use unsaturated polyester resin, epoxy resin, and phenolic resin as a matrix, and glass fibers or their products as reinforcing materials, also known as glass fiber-reinforced plastics. FRP has the advantages of light and hard, non-conductive, high mechanical strength, less recycling, and corrosion resistance, so it is widely used in various fields in industry. According to different substrates, FRP can be divided into unsaturated polyester FRP, epoxy FRP, and phenolic FRP. Due to the different types of resin matrix used, there are also great differences in the characteristics of FRP. But now cables often need to be buried underground, and their compressive strength, flexural strength and wear resistance are all poor. Contents of the...
