[0002] Nanocomposites are made of a matrix such as resin, rubber, ceramic and metal as a continuous phase, and modifiers such as nano-sized metals, semiconductors, rigid particles and other inorganic particles, fibers, nano-carbon tubes as a dispersed phase. The modifiers are evenly dispersed in the matrix material through appropriate preparation methods to form a composite system containing nano-sized materials. This system of materials is called nanocomposites. Nanocomposites have a wide range of applications in many fields due to their unique properties. The pressing device for producing this type of material is a key equipment in the preparation process, which directly affects the performance and quality of the composite material.

[0003] At present, during the production of existing nano-composite materials, the mold is heated to a set temperature, and a certain pressure is applied to the material through a pressure application system. Under the combined action of high temperature and high pressure, the material will undergo production deformation, and the particles will be tightly combined to form a dense composite material. After the required pressing time is reached, the material is allowed to cool to room temperature. Especially in the fiber fabric processing flow, since the single-layer fiber fabric is thin, it is easy to stick to the heating device during the heating process, resulting in damage to the single-layer fiber fabric, increasing production costs and reducing production efficiency.
