• What are the preparation methods of composite materials?

    The preparation methods of composite materials mainly include physical blending, chemical reaction, and hot-pressing molding methods. Among them, physical blending is used to mix two or more materials and then heat-treat them, chemical reaction is used to join two or more materials through chemical reactions, and hot-pressing molding is used to heat-treat two or more materials and press them into a shape.
  • What are the applications of composite materials?

    Compared to traditional materials, composite materials have the following advantages: lighter weight, higher strength, and better corrosion resistance. For example, carbon fiber reinforced plastic is only one-fourth the weight of steel but four times as strong.
