The superior performance of carbon fiber reinforced composite materials has outstanding performance in various industries such as wind power.
Resin-based composites are fiber-reinforced materials with organic polymers as the matrix. Through compounding, plastics have a variety of superior properties, and the application fields are further expanded.
It is speculated that China's resin-based composite material production in 2015 is expected to reach 5.3 million tons, of which thermoset composite materials output 3 million tons, and thermoplastic composite materials use 2.3 million tons. In the past few years, thermoset composite materials have always occupied most of the market share, but due to factors such as non-recyclability, difficulty in processing, and high production costs, some products have gradually been replaced by thermoplastic composite materials. Thermoplastic composite materials were developed in the 1980s. They belong to a new type of composite material with "high performance, low cost, and environmental protection", which can replace some expensive engineering plastics, non-environmental thermosetting composite materials and lightweight Metal (such as aluminum alloy) materials are widely used in aerospace, automobiles, wind power, electrical appliances, trains, sports equipment, construction, military and other industrial products. They are developing rapidly and provide materials with superior performance to meet the new development requirements of these fields. .
In the aerospace field, the performance requirements of components continue to push the performance of currently used metals and thermoset materials to the limit, and new materials need to be found. With the introduction of hybrid molding technology, Victrex combines the strength of PAEK continuously reinforced composites with the design of PEEK injection molding solutions. Compared with metal or thermosetting plastics, this overmolding takes several hours. The process can produce the same part in a few minutes. This technology not only achieves high specific strength, but also reduces weight by up to 60%, while integrating several parts into a simple and highly functional part.
In the automotive field, the application of composite materials has sprung up in recent years. Global automakers are facing extremely challenging new regulations on fuel economy and greenhouse gas emissions, and the demand for automobile consumption reduction has risen sharply. As one of the important lightweight materials, carbon fiber reinforced resin matrix composites (CFRP) have been affected by major automobiles. Favored by manufacturers. German BMW took the lead in launching the world's first mass-produced pure electric vehicle "i3" with a CFRP skeleton body. According to its carbon fiber raw material provider Mitsubishi Rayon, major European automakers other than BMW will also successively adopt CFRP in mass-produced vehicles with an annual production scale of 20,000 to 50,000 to meet the stricter European fuel efficiency regulations in 2020. . Toray's polyamide (PA) thermoplastic CFRP is used in the battery pack casing of Toyota's fuel cell vehicle MIRAI. This is the first time that CFRP has been used in automobile structural parts. Teijin and General Motors of the United States jointly develop thermoplastic CFRP parts for production vehicles, with the goal of producing tens of thousands of mass-produced vehicles annually. With the development of 3D printing technology, the world's first concept car manufactured using 3D printing technology also uses carbon fiber composite materials. Its body uses the Saudi Basic Industries Corporation (SABIC) LNPTM STAT-KONTM carbon fiber reinforced composite material. Due to its excellent strength-to-weight ratio and high rigidity, it can minimize the distortion during the 3D printing process, enhance the design aesthetics, and strengthen Operational performance.
CFRP is regarded as the mainstream material for automobiles in the future, but for a long period of time in the future, glass fiber reinforced thermoplastic composite materials will still be one of the main varieties of plastic composite materials. CFRP will be widely used in high-performance car bodies. However, due to high cost, it has not yet become a mainstream product.
Resin-based composite materials have also been widely used in the field of wind power. Large-scale unit capacity has become the trend of the world's wind energy development. The blade length has also increased from 30 to 40 meters to more than 60 meters. As the blade length increases, how to reduce the weight of wind turbine blades has become a common need for the wind power equipment industry. Faced with the problem, the application of carbon fiber composite materials in large blades has become a trend.
The performance superiority of resin-based composites is attracting more and more attention from more and more fields. With the decline in the price of related raw materials and the improvement of processing technology, the charm of composite materials will be vividly displayed in more fields. In order to promote the development of composite materials, this year's CHINAPLAS 2015 specially opened up a "composite and special materials" area in Hall 10.3 in Area B. Here, the industry can see a variety of the latest composite materials and their applications.
