They combine the advantages of different materials and have the characteristics of high strength, high modulus, light weight, corrosion resistance, wear resistance, etc. According to needs, materials that meet specific performance requirements can be designed. They are easy to process and shape and can be made into products of complex shapes. Polymer composite materials play an important role in modern industry and science and technology with their excellent performance and wide application.
