Two common processes for carbon fiber products

Carbon fiber material is lighter than aluminum, but its strength is better than most metal structural materials. It also has some performance advantages such as high temperature resistance and corrosion resistance. Therefore, carbon fiber products are popular used in aerospace, medical equipment, rail transportation, automotive industry and other fields. In this article we take a look at the molding process of carbon fiber products.

Heat compression molding:

The carbon fiber prepreg is placed between the upper and lower molds, jointing the molds and  placing on the hydraulic forming table, after a certain period of high temperature and high pressure to cure the resin, the carbon fiber products are released from molds. This molding technology has the advantages of high efficiency, good quality, high dimensional accuracy, and little environmental impact. It is suitable for mass production and high-strength composite parts. However, the early mold developing and manufacturing is complicated and the investment is high. The size of the parts is limited by the size of the pressing machine.

Autoclave molding：

The carbon fiber prepreg is laid in a predetermined direction to form a composite material Workpiece in a Autoclave , and the curing process is completed under a certain temperature and pressure. The autoclave is a special pressure vessel that can withstand and regulate a certain temperature and pressure range. The Workpiece is laid on the surface of the mold with the release agent, and then covered with porous anti-sticking cloth (film), suction felt, and air-felt, and sealed in a vacuum bag, and placed in the Autoclave . Before heating and curing, the bag is evacuated to remove air and volatiles, and then heated according to different resin curing systems, pressurized, and cured. The formulation and implementation of the curing system is the key to ensuring the quality of the autoclaved molded parts.
