Abstract
This article delves into the energy absorption characteristics of materials and their applications in the field of impact protection. The research background and significance lie in the fact that with the rapid development of modern industrial technology, there is an increasingly urgent demand for materials with excellent energy absorption performance, especially in fields such as automotive, aerospace, and construction. The energy absorption capacity of materials directly affects the safety and reliability of structures. The article first elaborates on the theoretical basis of material energy absorption mechanism, including material deformation and energy dissipation mechanism, dynamic response characteristics under impact load, and evaluation indicators of energy absorption efficiency, providing theoretical support for subsequent research. Subsequently, this article focuses on the optimization design methods of impact protection materials. Through the study of the energy absorption characteristics of porous structural materials, the analysis of the impact resistance of composite laminated structures, and the exploration of the energy absorption mechanism of gradient functional materials, new ideas are provided for the preparation of materials with high energy absorption capacity. In terms of engineering applications, this article studies the energy absorption characteristics of materials in the design of energy absorbing structures for automotive collision safety, the development of impact protection systems in the aerospace field, and the application of energy dissipation mechanisms in building seismic structures, verifying the practical application effects of the studied materials.
