Glass fiber reinforced composite is a kind of material which is made of glass fiber and its products as reinforced materials and matrix materials through a certain molding process. Glass fiber is a kind of filament drawn from molten glass. According to the composition of raw materials, it can be divided into alkali, non alkali, medium alkali and special glass fiber, such as high silica, quartz fiber and so on. Glass fiber products mainly include glass fiber cloth, felt and special three-dimensional fabric. According to different warp and weft yarn weaving methods, glass fiber cloth can be divided into N-pattern, twill pattern, glass fiber cloth, etc. Special three-dimensional fabrics can be divided into ply stitching, three-way orthogonal fabrics, multi axial diameter braided fabrics, two-dimensional multi-directional braided fabrics, etc. inorganic matrix (phosphate) and organic matrix (epoxy resin, phenolic resin, unsaturated polyethylene resin, etc.) are commonly used. Box matrix is generally aluminum alloy. The commonly used glass fiber composite material refers to resin matrix composite material, which can be formed by hand pasting, winding, pressing, injection and pultrusion. Because of its light weight, corrosion resistance, insulation and other characteristics, glass fiber reinforced composites can be widely used in mobile phone, chemical industry, transportation and other fields. In the military field, it can be used for radome, fairing, missile warhead and solid rocket motor ablative heat shield, missile launcher, firearms and structure parts of mountain fighting vehicles, etc

prospect

Automobile industry is a field where composite materials are widely used, especially in Europe. Due to the requirements of relevant laws and regulations, automobiles must meet the corresponding emission standards before 2020. In order to reduce emissions, lightweight is very important. Lightweight is the development trend of automobile industry, which brings great opportunities to composite materials. Material solutions are changing in the automotive, construction, energy, industry and transportation industries. From traditional materials to high-performance composites, which provides a market opportunity for the rapid promotion and use of high-performance composites. Materials science, especially composite materials, is one of the main driving forces to promote the development of technology. Due to the increasing market demand of glass fiber and its composites in automobile industry, the development of glass fiber and its composites industry is promoted. In terms of glass fiber, various glass fiber companies have developed various new glass fiber products suitable for automobile industry. In the glass fiber composite industry, the widely used SMC molding process was first developed for the automotive industry. In recent years, some new processes and products, such as long fiber reinforced thermoplastic, glass fiber reinforced thermoplastic sheet (CMT) and programmable powder pre molding (P4) are also developed for the automotive industry.

In the long run, with the strengthening and transformation of infrastructure in the Middle East and Asia Pacific, the demand for glass fiber has increased greatly. With the growing global demand for glass fiber in glass fiber modified plastics, sports equipment, aerospace and other aspects, the prospect of glass fiber industry is still optimistic. In addition, the application field of glass fiber is expanded to the wind power market, which may be a bright spot in the future development of glass fiber.

According to the latest forecast, driven by global industrial growth, the average annual growth rate of glass fiber market will be 7% in 2016. The global market value of glass fiber reinforced materials is 7 billion US dollars. The trend of global population growth and climate change makes glass fiber composite materials have the advantages of light weight, impact resistance, durability and high strength compared with traditional materials; its characteristics can meet the rapid growth market demand driven by sustainable development demand. According to statistics, 32% of the global glass fiber market is used in construction, including residential buildings, commercial buildings and water storage and transportation; 21% is used in industry, including factories, mining and offshore platforms; 8% is used in wind energy; 11% is used in consumer products, including household appliances, electronic products and entertainment; 28% is used in transportation, including cars, trucks, buses and trains.
