What are the molding processes of composite materials? Which private enterprises in China do better in composite materials?

The molding process of composite materials is the basis and condition for the development of composite materials industry. With the broadening of the application field of composite materials, the composite materials industry is developing rapidly, the old molding technology is improving day by day, and new molding methods are constantly emerging. At present, there are more than 20 molding methods of polymer-based composites, which have been successfully applied to industrial production. For example:

(1) hand paste molding process-wet paving molding method;

(2) spray molding process;

(3) resin transfer molding technology (RTM technology);

(4) forming by bag pressing method (pressure bag method);

(5) vacuum bag compression molding;

(6) Autoclaved molding technology;

(7) Hydraulic kettle forming technology;

(8) Thermal expansion molding technology;

(9) Forming technology of sandwich structure;

(10) production technology of molding materials;
