The composite material industry in India has a good development momentum

the composite material industry in India, which has maintained steady growth since 1996, produced 150000 tons in 2003, showing a good development momentum

it is reported that the composite industry in India developed during the 1970s, and the growth of the manufacturing sector has opened up new application fields in the construction, electronic insulation products and marine shipping sectors. Due to the efforts of glass fiber and resin manufacturers, a large number of small-scale companies were established. By the end of the 1970s, filament winding and dmc/smc molding processes began to develop. In the 1980s, new glass fiber factories viz.upt and DF entered the stage of rapid development after the establishment of torque 45 3G. After two glass fiber production plants were built in the late 1990s, the downturn that began in the late 1980s was changed. At the same time, factories for raw materials such as unsaturated polyester resin, epoxy resin, phenolic resin, initiator and accelerator have been established one after another. In this way, India has established a good composite industry, although its output is low compared with other Asian countries and regions such as China, South Korea and Taiwan

at present, India can produce 100000 ~ 150000 tons of FRP products every year. India also has a small carbon fiber factory to provide products for the aerospace sector. A lot of research and development work has been done on the development of aramid fiber and silicon carbide fiber, and unidirectional and bidirectional untwisted coarse gauze and composite felt have been established. On February 16, India has a large number of natural fiber resources, such as jute fiber, pineapple fiber, banana fiber, coconut fiber and bamboo fiber. The research work on ordinary or biodegradable natural fiber composites used for reinforcement is being carried out in several laboratories, and some products reinforced with natural fibers have been produced. Nevertheless, India still needs to import a considerable amount of reinforcement materials, especially high-tech products from advanced countries

India produces both thermosetting and thermoplastic composites. Unsaturated polyester resin was started by the hydrabad plant of bakelite hy Lam company, and many other companies followed in the mid-1960s. India also produces many commonly used additives, such as initiators, accelerators, reactive diluents, chemical thickeners, release agents, pigment pastes, fillers, etc., but many special chemical additives, including coupling agents, thixotropic agents that align the left side of the swing rod with the scribed line of the standard line plate when leveling, ultraviolet stabilizers, antioxidants, defoamers, need to be imported. There are still opportunities to produce these chemical additives in India

from the perspective of manufacturing technology, due to historical reasons and the need of low cost, the hand lay up process is still dominant in the molding process. However, more than 20 factories produce filament winding products, 9 units produce pultrusion products, 4 units produce SMC products and more than 25 units produce molded products. In addition, three advanced filament winding plants produce pressure vessels and CNG bottles, and three large-diameter pipeline plants use filament winding technology to produce water diversion, sewage discharge pipelines, tanks, wells, etc. The PVC brand is hs11300. Many hand paste units have recently upgraded their molding equipment with RTM and spray equipment

Indian composites have been widely developed in two fields. It is understood that first, aerospace, composite materials are directly oriented to rocket, aircraft parts, defense products; Second, the manufacturing industry, although developing slowly, is stable. India's aerospace sector is a composite material sector that applies the most advanced technology. The government has established several research and development laboratories for aerospace and defense sectors in particular. The products include all composite trainer aircraft, light fighter aircraft (LCA), advanced light helicopter (LAH), satellite and its engine parts, and several other defense products. These products are manufactured by Hindustan Airlines Co., Ltd. and several other laboratories as well as production units with special manufacturing capabilities. India has gained good capabilities in design and manufacturing, which can be compared with those advanced countries that produce these products. However, these processes and technologies have not developed and penetrated into other production sectors. Such high input, low income and high price raw materials hinder the promotion of these advanced technologies. This may also be the huge gap between the aerospace sector and production units in many advanced countries

most factories in the manufacturing sector are small and medium-sized enterprises, and no large enterprises produce a large number of products. This has led to the production of low-level products in the manufacturing sector and hindered the mechanical production process. India is not perfect in design, research, development, quality control and market. In order to make up for the shortage, the government made adjustments again, and established a quality control organization in the composite technology center of Indian Institute of technology in Madras and an engineering technology center in Mumbai. The Institute has established design and development institutions in rv-tifac, Bangalore and composite technology center, Indian Institute of technology, Mumbai. OCF and Saint Gobain Vetrotex in India have also established application development centers to promote the application of composites in the industrial sector

there is also a certain market for land transportation. Tip has been based in the land transportation sector, mainly the parts of various buses, trucks, train carriages, two wheelers and tricycles, and has provided parts to more than 60 companies. FRTP has entered the market of two wheelers and bicycles, mainly injection molded parts. In fact, FRTP is the main land transportation product in India. India produces cooling towers (containers), milk and chemicals Road transport tanks, front ends of trucks and buses, ventilation windows, train passenger water tanks, and railway sleepers. A typical example is a bus using 100-200 kg FRP

and offshore ships and structural members have also been developed. India has a long coastline and rich fishing industry, but FRP has not become the leading industry in the fishing industry and fishery market, and the products are not priced. About 12 companies produce boats, yachts, rowers and lifeboats. A lifeboat with a roof can rescue passengers on the burning ship in 10 minutes. This kind of lifeboat is advanced and praised. It was transformed by the community. In addition, the potential market for construction and civil public construction is huge. The construction department can use FRP doors to replace wooden doors, and can produce mezzanine, prefabricated Pavilion, shelter roofing materials, roof formwork, water tanks, decorative materials, furniture and public health projects. The chemical industry and its related industries accepted FRP from the beginning. Although the price is high, this material system has good chemical corrosion resistance. At present, FRP industry has achieved very good ability in the structural design and manufacturing of chemical plants. Some companies are exporting these products. The electrical application of FRP is closely related to the wide use of FRP in Indian power production. Due to its high-voltage insulation performance, FRP has been used in electrical transmission, electrical equipment, line switch transformers, electric arc furnaces and seals, and has also replaced the indoor doors of high-voltage transmission
