Electromagnetic heating rollers are widely used in industrial composite materials, such as fiber-based composite materials, pefe-based composite materials and metal-based composite materials. Next, we will discuss the definition and development of composite materials, and the development direction of fiber-based composite materials. The development direction of electromagnetic heating roller in industrial composite materials.

      "Composite materials" refers to two or more different materials under certain technological conditions to combine, absorb the characteristics and advantages of raw materials, make a new material with excellent performance and meet the new material characteristics. Generally, there are two main elements in the composition of composite materials: one is Matrix, the other is Reinforcement, which are combined to obtain a new material with high performance and reliability. According to this definition, composites can be divided into three categories according to the types of substrates: Polymer Matrix Composite (PMC), Metal Matrix Composite (MMC) and Ceramic Matrix Composite (CMC), whose classification is shown in Figure 1.


                                                                          

      Polymer composites (PMC) are the mainstream of composites industry at present. Fiber Reinforced Polymer Composites (FRP) are the main component of PMC. In practice, glass fiber reinforced thermosetting plastics and glass fiber reinforced thermoplastic plastics account for more than 90% of them, and become the most important. At present, there are more than 40,000 kinds of composite products in the world, and their application fields cover aerospace, military, satellite, industrial and civil fields. General market statistics still use fiber reinforced plastics as the established common composite method.


                                                                            

       The development of composites has been for many years. At present, the hottest topic in China is carbon fiber composites. With the support from the national level and the promotion of capital market, domestic composite materials have reached a certain scale of production, which has changed from pure labor-intensive industry to labor-intensive capital and technology-intensive industry. Composite materials have a wide range of applications, such as yachts, carbon fibre sports equipment, printed circuit boards and electronic grade. Fiberglass cloth and so on. Its products include yachts, fishing boats, wave boards, bathtubs, purification tanks, pipelines, barrel tanks, electrical and electronic components, automotive parts, rackets, clubs, fishing rods and so on.
