Problems solved by technology

However, in this paper, the resin matrix and glass fiber are directly compounded, and the compatibility between the two is poor. It is necessary to modify the existing glass fiber and then add it to the matrix resin.

Abstract

The invention discloses a graphene-modified polyester glass fiber reinforced plastic material. After low-temperature pretreatment is carried out on glass fibers through a physical method, the bending property, tensile property and interlaminar shear property of the glass fibers are improved. Through high-temperature treatment, oxidative decomposition of original gel on the surfaces of the glass fibers is achieved, and thus moisture stored and adsorbed by the glass fibers is removed. Graft modification is carried out on the surfaces of the glass fibers with materials such as porous carbon nanotubes through a chemical method, hole structures are formed, chain segments of some high polymers enter the holes when the glass fibers are compounded with a matrix, and an effect like anchoring is achieved. Thus, the bonding force between interfaces of the glass fibers and the polymers is increased, the impact resistance of the product is increased, and the obtained glass fiber reinforced plastic material has the advantages of being low in brittleness, large in toughness, low in formaldehyde content, large in tensile strength and the like.

Description

technical field [0001] The invention relates to the technical field of FRP, in particular to a graphene-modified polyester FRP material and a manufacturing method thereof. Background technique [0002] Toys are children's angels. Toys attract children's curiosity and attention with their bright colors, graceful and strange shapes, dexterous activities, and pleasant sounds. There are various types of toys and play methods, including plush toys, plastic toys, paper toys, electronic toys, wooden toys, metal toys, leather toys, educational toys, early education toys, fiberglass toys, children's cars and other miscellaneous items Toys, among which plush toys and children's cars are the best sellers. Metal materials and plastics are often used as materials for children's cars. Metal materials are not only expensive, heavy, but also prone to rust, while plastics are brittle, easy to break, and easy to age. Nowadays, FRP materials are mostly used instead of metal materials and pla...
