The composite material of our country is initiative 1958, use at war industry goods first, expand gradually after that civil. With the hand burnt craft developed a light boat of glass reinforced plastics 1958, mix with lamination roll make craft manufacture vitreous stencil steel, canal and rocket, development became the fibre glass that is used at long-range rocket 1961 - ablation of phenolic aldehyde colophony prevents hot warhead, introduced colophony of not saturated polyester, eject to shape with beehive interlining structure 1962 technology, the helicopter helix paddle that made glass reinforced plastics and wind tunnel lamina, of the same age begins to fiber twines craft to consider and produce the pressure vessel such as a bottle of a batch of oxygen. Created the radar fish trap of 44m of a diameter with structure of interlining of beehive of glass reinforced plastics 1970. From composite material of glass reinforced plastics changes direction gradually after 70 time civil. 1981 year of crop of composite material it is 15 thousand tons, achieve 65 thousand tons to 1986, year increase rate is 13% . Was affected insufficiently 1987 later by amount of breed of domestic raw material, develop Ceng Yi to spend backwater, during this, below the guidance of policy of reforming and opening, introduce foreign advanced technique in great quantities, if pool kiln was introduced in raw material respect,pull silk, short cut gauze of felt, surface felt, eject, twine gauze and the manufacturing technology of all sorts of brand colophony and auxiliary material. In shape the large reeving system that craft respect introduced production canal canister, help crowded technology product line, SMC product line, successive make trigger group, colophony deliver model aircrew, eject to shape inject of technology, colophony shapes the advanced technology such as the technology and equipment, formed research, design, production and raw material the industrial system with mutual wholer form a complete set, to 1995 crop of domestic glass reinforced plastics already achieved 165 thousand tons, the product is close 2000 kinds, have twine product line 120, SMC product line 31, BMC product line 5, draw crowded craft product line 100, spraying machine is stage of 260 stage, RTM70, continuous make trigger group 3, mechanization year productivity amounts to 250 thousand tons. To 1996, the product of glass reinforced plastics basically has the following sides: Cooling tower: Home has 200 more than manufacturer to produce cooling tower, produce per year many 20000, retain the quantity is 250 thousand, large tower of 3500 ~ 5000t/h already was popularized use. Twine products of canal, tin: Large canal canister of production is divided outside be being used domestic and internationally, still have partial export. Pull crowded product: Basically have window frame of profile of sucker rod, grille, electrical engineering ladder, door and tent support. Goods of SMC, BMC: Produce plywood of upper cistern group, chair and car part, produce per year a quantity to be 5000t. Car assembly: Outside removing the product that produces with SMC, return paste having a hand, eject and RT M goods, basically bodywork of door of bumper, around, car, biscuit, dashboard waits, goods is used except home outside still have a few export. Naval ships: Diminutive lifeboat, ship, houseboat, breed a boat to wait, produce per year about 6 ~ 70 thousand. Construction equipment: Building materials is the high quantity item of goods of glass reinforced plastics, if crock of tile of glass reinforced plastics, bath, building decorates column of anaglyph, Rome,wait. You Le and athletic equipment: The slide on water of glass reinforced plastics, touch oarage of lever of the animal model that touchs boat, park and nursery school, fishing, gig, skin, paddle, sledge to wait. Environmental protection establishment: Air conditioning implement, fan, cleaner, purify groove to wait. From the point of manufacturing technology, although introduced many advanced technique device, but utilization rate is not high, all goods still have 80% is a hand paste shapes, only 20% by twine, pull the equipment such as crowded, SMC and RTM to shape, the manufacturing latent capacity of industry of glass reinforced plastics is very accordingly large. The research application of advanced composite material basically is centered at national defence industry. High-powered colophony base composite material, basically be carbon fiber enhances epoxy resin with fiber of fragrant black silk ribbon, much more luscious round epoxy resin and BMI, the performance of composite material is steady, already threw application in great quantities, the composite material that is equivalent to T300/PMR-15 function already developed a success, a batch high-powered thermoplastic colophony radical composite material, wait to be being moved toward from the lab like PEEK, PECK, PPS practical. Component of advanced composite material is in by second bear force to advocate bear force transfer. In shape craft respect, glass reinforced plastics of have the aid of of advanced composite material shapes the change that the technology implements to paper mechanization automation by the hand stage by stage. But total level and foreign advanced technique still have certain space.
