Mitsubishi Rayon, which is located in Chiyoda-ku, Tokyo, Japan, has successfully developed a medium-elastic modulus carbon fiber "パ イ ロ フ イ ル" MR70 with greatly improved properties based on the previous medium-elastic modulus carbon fiber. There are sports, entertainment products, etc., which are the areas where material weight reduction is most desired, and the strength of materials is increased for weight reduction. At the same time, it is indispensable to improve the stiffness (elastic modulus) due to light weight and thin wall.
It has previously been difficult to increase both carbon fiber strength and elastic modulus. The MR70 developed this time has a strength of 7GPa and an elastic modulus of 324GPa. It is found that this is based on the company's previous medium-modulus carbon fiber MR60H, which has increased strength and elastic modulus by about 20% and 10%, becoming an epoch-making medium elasticity. Modulus carbon fiber.
The high-performance carbon fiber is re-evaluated through the manufacturing process of the precursor filament and the carbon fiber. By controlling the fine structure of the carbon fiber, it is possible to eliminate defects and achieve high-performance products.
The product has been produced in domestic production facilities. The company has been focusing on aircraft, sports and entertainment applications, and has begun to provide samples to relevant manufacturers. In addition, the company is expanding its supply and listening to user evaluations, while seeking to accelerate the development of higher-performance carbon fibers for the aircraft, high-performance industry, sports and entertainment applications.
