Comprehensive Analysis of Composite Material Structure Design

Self-lubricating composite materials utilize the complementary properties of various materials, either without adding lubricants or by adding a small amount of solid lubricants, to create a lubricating film on the surface through the action of frictional heat, thereby reducing friction and wear. These materials can be applied in extreme operating conditions, such as high temperatures, heavy loads, and situations where the lubricating oil film is prone to failure. By leveraging the self-lubricating properties of components, wear can be minimized, and service life can be extended. Inspired by biological structures and their functions, bionic structural materials with good tribological properties are developed, involving the cross-disciplinary theories of various fields. Based on homogenization theory and finite element analysis methods, this study analyzes the optimization design of high-temperature self-lubricating composite material structures, providing a theoretical basis for the development of bearing materials with excellent mechanical properties and high-temperature self-lubricating performance.
