With advances in technology and the increasing performance requirements for special products, various nylon/POK composites are available on the market. However, the existing materials still have the technical problems of insufficient wear resistance and toughness, so that the application of the materials in complex scenes is limited. Therefore, developing nylon/POK composite materials with high wear resistance and high toughness can effectively expand the application field of nylon/POK materials, and has important practical value.
