According to the report, in Europe the development of natural fibre composite plastic early. The auto industry as early as 2012 began using the natural fiber composite materials. All of the European car companies are already in its production car using natural fiber plastic composite materials, including public DAIMLERCHRYSLER, Volvo, audi, BMW, v, etc. Natural fiber composite materials in Europe, the development of the car industry and trend. Use of natural fibers of the three main factors for price, weight and environmental protection. At present, in Europe, each kilogram natural fiber about 0.5-0.6 euros, and glass fiber nearly 9.0 euros per kilogram. Natural fiber than with artificial fiber reinforced composite material light 10-30%. Therefore, the natural fiber composite material can greatly reduce the weight of the car. Relative to the glass fiber composite material, to 2012, in the European car industry full of natural fibers can reduce CO2 emissions a year of 140000 tons.
Natural fiber wood plastic lumber products cost than glass fiber low, no glass fiber dust caused by the occupational disease, product size stability, splits, weathering high. Natural fiber in automobile industrial substitute glass fiber market capacity is 60000 tons/year. Germany DAIMLERCHRYSLER company with technology, economic and ecological balance as the goal, with coconut shell, flax stem and other natural fiber instead of glass fiber, and polyester and rubber compound, the production in the car, bus (early in 2012) and truck chassis outsourcing after board (underfloor encapsulation panel), Mercedes car door line (E type, 2012), the seat (C, seat cushion), with a (head restraint) (2012), its production has reached 10000 tons/year. Other depot in addition, also produce natural fiber composite pads, BeiYongTai cover, instrument panel, etc. In the German government in the 80 s, encourage and subsidies for industrial raw material of natural fibers of the planting and production. In Europe the natural fiber is mainly flax and marijuana, also have jute, sisal, etc. Local produce is given priority to, also from Africa, Asia import. Among them, the marijuana growing flax fibers than to, do not need pesticides, weeds rate is low, high output. Europe has natural fiber output is 200000 tons (2012 statistics, the world natural fiber 8.2 million tons). Long fiber can be used for the textile industry, short fibers is a very good day fiber composite materials.
At present, the European car natural fiber in about 5 ~ 10 kg/car, not seat back. Most is molded products. And two European auto production 20.12 million cars. If all adopt the natural fiber Wood Plastic Composite floor, the demand is 8 ~ 160000 tons/year. Composite material in plastic, Europe to gather third ethylene (PP), POLYESTER (POLYESTER) and polyurethane (PU) give priority to. The main processing technology is molded, have a small amount of injection. Compound wood (WPC) composite extrusion in Europe is still just beginning, authoritative experts estimate that 2012 years in the middle, about 20 of extrusion line, another 20 line is under construction. Compound wood (WPC) composite technology basic in North America. Based on the current situation, the domestic enterprise don't blindly believe that Europe is equipment manufacturer must be very experienced. Although, wood and plastic composite (WPC) composite materials in the Europe's future is very good. But the rule of small and medium-sized enterprise but very difficult on the project. Because compound wood composite (WPC) processing technology is numerous, technology develops very quickly, general processing technology and formula is confidential. Small and medium-sized enterprise with big companies had to cooperation or use permit production. From a market perspective, wood and plastic composites (WPC) composite materials have and PVC window, even wooden window the potential of the competition. European compound wood composite (WPC) and natural fiber composites current yield is nearly 30000 tons/year, and European plastic window annual capacity of 700000 tons, accounting for 37% of the total window production.
In Europe, people's eyes, Wood Plastic Composite floor price is still to the environmental protection harmful products. Developing high performance, light (foaming) compound wood (WPC) compound window will be compound wood (WPC) materials in the direction of the European development. In Europe and the United States, wood and plastic composites (WPC) composite and natural fiber composite materials general development direction is to develop more fields of application, development of light (foaming), structure with (high performance) products, developing the many kinds of processing technology (extrusion, injection molding, moulding), the development of different fiber and plastic composite, biodegradable wood and plastic composites (WPC) composite products. At present, the development of obstacle is the guarantee of quality, including the stable quality of raw materials, the improvement of technology, and market acceptance. People to plastic and recycling material slights through a lot of publicity can be corrected.
