Abstract

The invention relates to a composite material, and in particular discloses a self-repairing multifunctional composite material structure. The self-repairing multifunctional composite material structure includes a composite material main body, which is characterized in that: the upper surface of the composite material main body is coated with a three-dimensional metal network, the lower surface is coated with a planar metal network, and the upper surface of the three-dimensional metal network is coated with a The upper cover plate of the composite material, the lower surface of the planar metal network is pasted with the lower cover plate of the composite material. The invention increases the strength and modulus in the thickness direction of the composite material, increases the interlayer fracture toughness and the ability to resist delamination generation and expansion of the composite material, and increases the anti-impact damage ability and fatigue-resistant delamination expansion ability of the composite material .

Description

(1) Technical field [0001] The invention relates to a composite material, in particular to a self-repairing multifunctional composite material structure. (2) Background technology [0002] Due to the advantages of specific stiffness, high specific strength, good corrosion resistance, and designable performance, fiber-reinforced resin-based composite materials have become a new generation of high-strength and lightweight structural materials, and are widely used in aviation, aerospace, automobiles and other fields. However, limited by the characteristics of the laminated structure, composite laminates are prone to cracks between laminates due to normal loads and foreign object impacts during service, which is also called delamination damage. [0003] Delamination damage is the most common type of damage in laminated structural composites, and it is difficult to be detected conveniently and reliably because it occurs inside the laminate. At present, the delamination damage de...
