[0002] As a high-performance automobile subframe, carbon fiber subframe is used in high-performance automobiles, high-end electric vehicles, special vehicles and modified vehicles. Autoclave molding is a common manufacturing process for carbon fiber subframe molding. The current carbon fiber subframe autoclave molding process includes the following steps: 1. Prepare raw materials such as embedded metal parts, carbon fiber prepreg and foam; 2. Design and manufacture carbon fiber subframe molding molds, design carbon fiber prepreg ply, and use CNC machining technology to process the foam into a foam core with the overall frame shape of the subframe; 3. Install the embedded metal parts on the foam core to form the main frame, and lay the carbon fiber prepreg on the main frame according to the layup design to form a composite material frame; 4. Place the composite material frame into the molding mold, seal the molding mold and place it into the autoclave to cure the prepreg under high temperature and high pressure; 5. After hot pressing, the subframe is machined, the bushing is pressed in by a press, and the parts are assembled; 6. Perform quality inspection on the subframe.
