Formula of glass fiber composite

Abstract

The invention discloses a formula of a glass fiber composite, and relates to the field of glass fiber. The composite comprises the following raw materials by weight: 12 to 13 parts of EW-200 glass fiber plain cloth, 14 to 16 parts of phenolic resin, 10 to 12 parts of barium titanate powder, 9 to 12 parts of a coupling agent, 7 to 9 parts of bamboo fiber felt, 6 to 8 parts of triethyl citrate, 3 to 5 parts of polypropylene powder, 7 to 9 parts of epoxidized soybean oil, 12 to 13 parts of bisphenol epoxy resin, 15 to 18 parts of dicumyl peroxide, 14 to 16 parts of maleic anhydride grafted polypropylene, and 20 to 25 parts of glass fiber. The glass fiber composite prepared according to the formula is light in weight, high in strength, and high-temperature resistant; due to the addition of barium titanate powder, the dielectric constant of the glass fiber composite is improved. The preparation method of the glass fiber composite is simple in process, and can be carried out on conventional equipment; the glass fiber composite is excellent in strength, rigidity and impact strength; the process is simple; the cost is low; the production efficiency is high.

[0002] With the development of the battlefield environment, in order to improve the battlefield survivability of tactical missiles and effectively suppress and destroy enemy air defense or early warning systems, the flying speed of missiles is getting faster and faster, and the range is getting farther and farther. Therefore, tactical missiles have begun to put forward more weight requirements. Due to the high density and poor toughness of the material itself, the weight of the product is relatively high. The use of resin-based composite materials in the radome can greatly reduce the cost of the radome. weight; but most resin-based composite materials have poor temperature resistance, so the range of use is small. With the continuous enhancement of "ecological awareness", people pay more and more attention to environmental protection and health. Among them, excellent processing performance, The environmental pollution caused by plastics used in various industrial products has become a common concern. In particular, fiber-reinforced composite materials are usually composed of glass fibers, carbon fibers, etc. and plastics. Disposal is difficult and the production environment is harsh. It has added a great burden to the environment. Therefore, natural fibers such as bamboo, hemp, and wood fibers have attracted people's interest in development and application because of their light weight, low price, easy availability, biodegradability, and no pollution to the environment. Although the surface of glass fibers is generally treated with a coupling agent, since polypropylene is a non-polar polymer material, the interface bonding strength with glass fibers is poor, even if some acid anhydride grafted polypropylene is usually used to improve the interface adhesion. However, the improvement of the performance of polypropylene by glass fiber modification is still limited
