Abstract

The invention relates to an upper beam assembly made from hybrid fiber composite material for an auto radiator and a manufacturing method thereof. The upper beam assembly comprises an upper beam body,a reinforcing plate and a foam sandwich layer, wherein the upper beam body is formed by integrally molding resin infiltrated carbon fibers / glass fiber fabrics under high pressure; the reinforcing plate is formed by integrally molding the resin infiltrated carbon fibers / the glass fiber fabrics under high pressure; and the foam sandwich layer is arranged between the upper beam body and the reinforcing plate. The manufacturing method comprises the following steps: 1) selecting suitable materials; 2) cleaning molds and coating release agents; 3) coating gel coats; 4) layering fibers and mountinginserts ; 5) clamping matched molds; 6) pouring resin; 7) solidifying the resin; and 8) opening the molds and stripping the molds. The structural rigidity and the structural intensity of the beam assembly for the radiator are improved, reducing weight is realized, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of composite materials and auto parts, in particular to an upper crossbeam assembly of a hybrid fiber composite material automobile water tank and a manufacturing method thereof. Background technique [0002] Due to the higher and higher requirements on the shape and performance of the car, affected by the shape, the seams of the front part of the car are of different heights, coupled with the limitation of the space of the engine compartment itself, and the types of parts layout are increasing. Parts mounting points are more or less arranged on the water tank cross beam assembly, and the connecting device lock body mounting part of the engine cover assembly makes the load of the water tank cross beam assembly heavier and heavier. As an important structural part of the car body, the water tank beam assembly, considering the lightweight requirements of the body structure, as well as the requirements for high structural...
