AI Technical Summary
Existing carbon fiber sheets, while maintaining lightness and thinness, struggle to simultaneously meet the requirements of high strength and stiffness. Furthermore, the mesh-like carbon fiber is prone to deformation at the sides, and the thicker external curing adhesive leads to an increase in overall thickness.
The blended fabric layer is made of carbon fiber filaments and titanium wires, and is laid in alternating layers with carbon fiber mesh. It is protected by curing adhesive and uses molding molds and cylinder system for curing and unloading operations to ensure the thinness and strength of the carbon fiber sheet.
It achieves improved overall strength and stiffness of carbon fiber plates while maintaining a relatively thin thickness, avoids deformation of the mesh-like carbon fibers, and protects the internal structure through curing adhesive.
