The core technical advantage is fast curing at low temperature, which can be cured in 15-30 minutes at 60-80℃, reducing the production cycle by more than 60% compared to ordinary epoxy prepregs. It has excellent adhesion to metal substrates, good impact resistance and corrosion resistance, and meets IATF 16949 automobile industry certification. It can reduce the weight of automobile parts by 30% compared to traditional steel parts, improving the overall performance of new energy vehicles. It also has good surface quality and molding adaptability, meeting the high-quality requirements of automobile interior and exterior parts.
The base fiber is T700 carbon fiber with a diameter of 7μm, matched with low-temperature fast curing epoxy resin system. The thickness range is 0.2-2.5mm, standard roll width is 1250mm, and the fiber volume fraction is controlled at 58±2%. The curing temperature ranges from 60 to 80℃, with a curing time of 15-30 minutes, a bending strength of 4800MPa and impact strength of 30kJ/m². The volatile content is no more than 0.25%, and it can be stored in a dry normal temperature warehouse at 5-25℃ with a shelf life of 6 months. It is suitable for hot press molding and automated layup processes, and can be customized into different specifications according to customer needs.
This prepreg is widely used in new energy vehicle battery pack shells, automobile body structural beams, interior decorative panels, charging pile components, and various lightweight structural parts of commercial vehicles. It can also be applied to new energy bus body parts, logistics vehicle lightweight components and other automobile manufacturing scenarios, helping enterprises achieve the goal of carbon neutrality in the automotive industry.
