Research on the Application Effect of Composites in the Weight Reduction of Small Mechanical Parts

This paper focuses on the application of plastic-fiber composites in reducing the weight of small mechanical parts. With the development of industry, there is an increasing demand for lightweight mechanical parts. Plastic-fiber composites, due to their unique properties, have become a potential alternative to traditional metal materials. This research conducts a series of tests on plastic-fiber composites, replacing metal parts with composite parts and comparing their strength and weight reduction effects. The results show that plastic-fiber composites can achieve significant weight reduction while maintaining satisfactory strength, providing a new solution for the lightweight design of small mechanical parts.
