Abstract

The invention discloses a preparation method of an impact-resistant self-recovery bionic composite material, and relates to the technical field of composite materials, a memory alloy NiTi bionic structure is adopted as a composite material matrix, and NiTi shape memory alloy has high elasticity and a shape memory effect, so that the impact-resistant energy-absorbing effect of a composite interlayer material can be enhanced. The excellent functional characteristics of a bionic structure are integrated, the morphological characteristics of a bionic matrix model can be replaced according to requirements, through the use of the NiTi shape memory alloy, the structure can recover the original morphology of the structure under the control of an intelligent temperature control system after the structure is subjected to excessive impact energy and has plastic deformation, and the subsequent recycling of the structure is facilitated. Foamed aluminum and basalt fibers are mixed to prepare a carbon fiber interlayer-NiTi bionic structure-basalt foamed aluminum composite material sandwich plate, and the overall mass is reduced.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a preparation method of an impact-resistant self-restoring bionic composite material. Background technique [0002] With the rapid development of science and technology, people have higher and higher requirements for material performance. It is hoped that the quality of materials and the use of materials can be reduced while ensuring that the properties of materials such as strength and hardness meet the requirements, so as to achieve cost savings. Purpose, such materials are used in automobiles, ships, etc., and the reduction in product quality can greatly reduce the energy loss during driving, which is both environmentally friendly and efficient; however, existing transportation equipment such as automobiles, ships, etc. When the profile is seriously damaged, it is difficult to recover for secondary use, and the impact resistance is insufficient, and the cushioning ...
