AI Technical Summary
Composite laminate structures have weak interlaminar properties, are prone to delamination, and have low impact damage tolerance. Existing toughening technologies suffer from complex processes and insufficient optimization of interface layup design.
By introducing interlayer links into the composite material structure to form an interlocking structure between the layers, optimizing the layer design and sequence, and using interlayer fiber/fabric links for bonding and locking, interface strengthening is achieved.
It improves the interlaminar properties of composite materials, slows crack propagation, and enhances resistance to impact damage and fatigue crack propagation. It is suitable for dissimilar material systems with large differences in material modulus.
