FRP is a kind of glass fiber composite material, and its comprehensive performance is relatively good. Therefore, the product is widely used, involving more than 20 industries and covering almost all industrial sectors of the national economy. Among them, the largest number of applications are in the chemical, construction, power, light industry, petrochemical, electromechanical, and automotive industries. China's sophisticated glass fiber composites have been widely used in the aviation industry. Currently, this composite material is used on both civilian and military aircraft. The reason why glass fiber is favored in this field is because it is a new type of functional material and structural material, and has a series of excellent characteristics such as high temperature resistance, corrosion resistance, high strength, small elongation, and good insulation. The composition of glass steel Glass fiber is an inorganic non-metallic material with excellent performance. It is based on natural ore. After scientific calculation and reasonable ratio of various raw material components, it is homogenized by high-temperature melting, drawing, winding, weaving. Cloth and other processes finally formed a variety of products. The diameter of glass fiber monofilaments ranges from a few micrometers to more than 20 micrometers, which is equivalent to 1/20-1/5 of a hair filament. Each fiber bundle has hundreds or even thousands of monofilaments. The outstanding characteristics of glass fiber are high strength, high elastic modulus, low elongation, electrical insulation, corrosion resistance, etc., and are widely used as reinforcing materials, electrical insulation materials, and thermal insulation materials in composite materials. In all areas of the national economy. FRP is a composite material in which a thermoplastic resin is combined with glass fiber, carbon fiber, and polyamide fiber. Usually, the mixture of these materials is melted and kneaded to form pellets and molded by injection molding. There are also molded sheets made of long fibers and pressed into press molded sheets. The former is intended to improve the properties such as heat resistance, dimensional stability, impact strength, or electrical conductivity of various resins by using fiber-reinforced materials. The latter aims to produce large-sized products and focuses on the influence of the orientation and content of the fibers. The thermoplastic resins used are various, such as AS, ABS, PA, PBT, PC, PET, POM, PPS, etc. and high-performance engineering resins, which are used according to their different characteristics. Footwear application In recent years, due to the trouble of security inspection, steel safety toes have gradually been replaced by other non-magnetic materials, and the application of fiberglass as a safety shoe toe is an ideal choice. Maojie Shoes Co., Ltd. took the lead in the development of a fiberglass safety toe cap. Through a large number of experimental R&D and final product testing, it finally screened out the ideal formula to produce a high-quality explosion-proof glass fiber safety toe cap. In September 2005, it was granted a utility model patent by the Chinese Intellectual Property Office. The patent number is ZL 2004 2 0091735.1. According to testing, the indicators of the explosion-proof fiberglass safety footwear produced by Maojie fully comply with the requirements of the EN-CSA-ANSI standard for safety shoes. It can be heat-resistant at 200°C, cold-resistant at -40°C, and is also resistant to acids and alkalis. It can meet the needs of the footwear production process and is suitable for wearing environments with severe weather. Experiments show that the fiberglass safety toe is very environmentally friendly, no recycling, long-term ultraviolet irradiation can be naturally decomposed; with anti-static function, and anti-bacterial, non-toxic, non-volatile objects; In addition, there is ultra-thin and ultra-thin, safety is not Deformation and other advantages can absorb and decompose the impact force. When encountering a great impact, the toe cap will be radially cracked, and will not sag and deform like a steel head, so it will not hurt the foot, thus providing excellent protection. In the production of safety toe caps, steel toe caps use steel molds, and the cost of molds required to change shapes is higher, but the cost of molds for fiberglass toe caps is lower. For the shoe factory, the process does not need to be changed, so it can be easily applied. And compared to steel, aluminum and other alloy toe, fiberglass toe more easily bonded with the material, processing more convenient. In terms of end-user applications, in addition to enjoying the basic safety features, because of the lighter weight of the fiberglass toe, the wearer will feel more comfortable and will not lose balance due to heavier head and lighter weight. In addition, Maojie Shoes Co., Ltd. has also applied glass fiber reinforced plastics with good resilience to develop fiberglass elastic pads. The fiberglass elastic pads can be used alone or combined in ordinary insoles. The fiberglass stretch pad is molded in a standard foot shape and has a good ability to correct walking posture. The shock-absorbing midsole elastic insole is treated with moisture wicking technology and has excellent shockproof, antibacterial, odor-removal, perspiration, breathability, and comfortable foot feel. It is suitable for all types of shoes. The biggest advantage is its rebound function, so that the wearer's feet evenly, but also because of the glass fiber in the glass fiber arranged in a crisscross pattern, with a strong anti-nail puncture effect. At present, the global concept of environmental protection has been further strengthened. The steel toe cap cannot be separated due to its close fit with leather or lining materials. It is difficult to separate and recycle waste during waste disposal. However, the fiberglass toe cap and shoe upper material can be naturally decomposed and is in good agreement with it. Environmental trend. FRP elastic insoles also play a stab-resistant effect on the lumbar iron in safety shoes. Their corrosion resistance, oxidation resistance and excellent springback-free deformation characteristics are bound to be more and more popular in the industry.
