Abstract
The invention discloses a molding process of a composite automobile B-pillar and a molding device thereof. The molding process includes: chemically treating the skin of a metal skeleton before use; stacking carbon fiber prepregs and metal skeletons in sequence in a die-casting mold , carbon fiber prepreg, and combined film compression molding; demoulding after molding to obtain a composite automobile B-pillar. The forming device comprises a metal forging structure (10) and a die-casting structure which are arranged in sequence, and a butt transfer structure (20) is provided between the metal forge structure (10) and the die-casting structure, and the butt and transfer structure ( 20) The metal skeleton processed by the metal forging structure (10) is bonded and butted with the carbon fiber prepreg and then transferred to the die-casting structure. The invention solves the technical problems that there are certain defects in the performance of the bonded automobile B-pillars in the prior art, and the bonding operation is difficult to effectively realize mass production, resulting in low production efficiency.
Description
technical field [0001] The invention relates to the field of automobile B-pillar manufacturing, in particular to a molding process of a composite automobile B-pillar and a molding device thereof. Background technique [0002] The B-pillar of a car refers to the column between the front and rear doors of the car, which connects the roof and the chassis of the car, and plays a vital role in the strength of the side of the car. When the car has a side collision, the B-pillar will bear most of the impact force. [0003] At present, automobile B-pillars are often manufactured by bonding metal layers and carbon fiber composite layers. The metal layers used here are also generally made of steel, so as to meet the mechanical properties and greatly reduce the structural weight and achieve the effect of lightweight. . [0004] However, this method is mainly based on the bonding between the carbon fiber composite layer and the steel plate. The performance of the bonding part will grea...
