The core advantage of T700 unidirectional carbon fiber prepreg lies in its precise fiber arrangement and resin wettability control. It adopts unidirectional layup design to maximize the tensile strength in the fiber direction, and the resin content is stabilized at 35±2%, avoiding the problems of increased weight due to excessive resin or insufficient interlayer bonding force due to too little resin. The EP2500 epoxy system used has excellent weather resistance and fatigue resistance, and can be used stably for a long time in the environment of -60℃~120℃, adapting to the stringent environmental requirements of the aerospace field. Compared with traditional aluminum alloy materials, the components formed by this prepreg can reduce the weight by more than 40% while increasing the strength by 2 times, effectively helping customers achieve lightweight design goals, and the storage conditions are controllable, which can be stored for 6 months at -18℃, facilitating large-scale production and stock preparation.
