< BACK good news! NFD carbon fiber composite plastic achieves a major breakthrough! 2020-01-08 11:34:17 High-performance carbon fibers from western countries have been restricted from exporting to China, and composite carbon fiber materials that can be used for military purposes have been strictly controlled. Limited by comprehensive factors such as technical conditions in China, coupled with backward formula design and production technology, the development of high-performance carbon fiber composite plastics is very slow. As high-performance carbon fiber composite plastics have been monopolized by foreign giants for a long time, high-performance carbon fiber composite plastics are expensive and difficult to purchase. Domestic companies often encounter situations where there is money and no materials. Therefore, Jiangsu Xinfuda Composite Materials Co., Ltd. (NFD) focused on the development of carbon fiber reinforced composite materials. After two years of technical research, technicians successfully developed high physical strength, high heat resistance, high wear resistance, chemical resistance, Compared with carbon fiber reinforced engineering plastics imported from abroad, the high modulus carbon fiber reinforced plastics show that the performance strength is significantly better than imported products. NFD's new high-strength carbon fiber reinforced composite plastic has excellent mechanical strength and impact resistance, high dimensional stability, and low warpage. New formula improves material performance by 30%! Hepla® H9000-XCF series carbon fiber reinforced plastic based on high-temperature nylon, with bending stiffness exceeding 52GPa! Bending strength is up to 520MPa! The tensile strength is up to 360MPa! Hepla® H7200-XCF series based on PA66 has a tensile strength of up to 315MPa! The outstanding mechanical properties of NFD carbon fiber composite plastic can easily replace most metals. The molded parts are 75% lighter than steel and 40% lighter than aluminum, which can provide a better solution for automobile lightweight and other industries. Program! The following figure shows the comparison of the physical parameters of Hepla® H7230-XCF (high strength 30% carbon fiber) with the parameters of Hepla® H7230CF (30% carbon fiber) and Hepla® H7230GF (30% glass fiber).
