Description

Technical Field

[0002] Composite materials are multiphase materials composed of two or more materials with different properties combined by physical or chemical methods. These materials can include metals, inorganic substances, organic substances, polymer materials, fiber-reinforced materials, etc. The preparation and application of composite materials are becoming more and more extensive in modern production and life. However, in the preparation process of composite materials, it is often necessary to heat, melt or soften the raw materials in order to carry out composite molding. Therefore, the heating device plays a vital role in the preparation process of composite materials.
