AI Technical Summary
Existing technologies make it difficult to manufacture high load-bearing capacity continuous fiber reinforced composite minimal surface structures, and it is also difficult to balance structural performance and function. In addition, the weak Z-axis performance limits its application in aerospace and other fields.
Using a three-period minimal surface structure as the framework, a lattice structure is formed by interlacing continuous fibers in the connected channels. Combined with fused deposition modeling 3D printing and ultrasonic vibration impregnation technology, a continuous fiber mesh composite minimal surface superstructure is prepared.
It achieves high load-bearing capacity and multi-functional integration of minimal curved surface structure, especially with a significant improvement in Z-axis performance, meeting the application requirements of aerospace and other fields.
