Abstract

The invention discloses a carbon fiber composite material front-end reinforcing beam and a preparation method thereof; the carbon fiber composite material front-end reinforcing beam comprises a front-end reinforcing beam body and reinforcing ribs, and the front-end reinforcing ribs are located on the back surface of the reinforcing beam body; reinforcing layers are arranged on the peripheries of the reinforcing ribs. The thickness of the reinforcing layer is linearly reduced from one side of the reinforcing rib to the surface of the reinforcing beam body at the front end; the preparation method comprises the following steps: (1), performing raw material punching and layering; (2), performing pre-vacuumizing; (3), putting the product into a mold; and (4), performing SMC forming. The carbon fiber SMC sheet is adopted, and through the design of the variable-thickness reinforcing layer structure, the design of the reinforcing beam body of the bow-shaped structure, the pre-vacuumizing treatment and the design of the mold entering angle of the laminated sheet, the problems that reinforcing ribs of a finished reinforcing beam at the front end of the carbon fiber composite material shrink and the porosity is high are effectively solved; the surface of the obtained formed product has a bright forged carbon pattern effect, is high in apparent mass, has excellent rigidity, mechanical property, first-order inherent frequency and deformation resistance, and is excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a carbon fiber composite material front reinforcement beam and a preparation method thereof. Background technique [0002] Traditional fuel vehicles have increasingly urgent requirements for fuel consumption regulations and new energy vehicles for cruising range, and vehicle lightweight has become an urgent demand for domestic automobile OEMs. The lightweight of the car can reduce the quality of the vehicle, improve fuel efficiency, increase the cruising range, and thus reduce the cost of using the car. [0003] The reinforcement beam at the front end of the car is one of the important parts of the side structure of the engine compartment, and it is one of the force transmission paths of the frontal collision. Traditional automobile front-end reinforcement beams are generally made of steel through stamping and welding processes. The products are not only heavy, but also require many as...
