Abstract

The invention discloses a carbon fiber composite automobile radiator upper cross beam assembly and a manufacturing method of the carbon fiber composite automobile radiator upper cross beam assembly, and belongs to the field of composites and automobile parts. The automobile radiator upper cross beam assembly at least comprises an upper cross beam body and a reinforcing plate, and a foam interlayer is arranged between the upper cross beam body and the reinforcing plate. High-strength light carbon fiber textile materials in multiple layers in the multi-laying-layer direction are adopted as reinforcement, resin is used as a base body for manufacturing, under the condition of meeting strength, rigidity and loads, light weight is achieved, the weight of the upper cross beam body can be reduced by 63%, the weight of the reinforcing plate can be reduced by 61%, and fuel efficiency is obviously improved. The Z-direction rigidity of the carbon fiber composite automobile radiator upper cross beam assembly can achieve 424N / mm, and meanwhile the rigidity of an engine cabin front cross beam system assembly is improved. Due to the fact that the structure of the carbon fiber composite automobile radiator upper cross beam assembly is greatly simplified, one-time processing forming is facilitated, and manufacturing cost is effectively lowered.

Description

technical field [0001] The invention relates to the field of composite materials and auto parts, in particular to a carbon fiber composite material automobile water tank upper beam assembly 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 strength a...
