The core technical advantages include ultra-high tensile strength up to 4900MPa, low volatile content that meets aviation environmental protection requirements, and precise fiber volume fraction control to ensure consistent structural performance across the entire roll. Compared with ordinary industrial prepregs, it has better resistance to extreme high and low temperatures and cosmic radiation, adapting to the harsh operating environment of aerospace. It also passes AS9100 and FAA certifications, ensuring full compliance with aerospace manufacturing specifications, and provides reliable support for high-precision and high-standard composite component production.
The base material is T700 carbon fiber with a diameter of 7μm, matched with bismaleimide epoxy resin system. The thickness range is 0.15-2.0mm, standard roll width is 1000mm, and the fiber volume fraction is controlled at 60±2%. The curing temperature ranges from 120 to 180℃, with a modulus of 230GPa and bending strength of 5200MPa. The volatile content is no more than 0.15%, and it needs to be stored in a dry low-temperature warehouse at -18℃ with a shelf life of 6 months. It is suitable for autoclave molding and hot press molding processes, and can be customized according to customer requirements for special specifications.
This prepreg is widely used in commercial aircraft fuselage and wing structural parts, military drone body components, rocket fairing linings, satellite load-bearing structures, high-end wind turbine blade reinforcement layers, and aerospace interior decorative structural parts. It can also be applied to high-precision industrial equipment components that require ultra-high strength and lightweight performance, helping customers meet the highest standards of the aerospace industry.
