Abstract

The invention discloses a carbon fiber automobile bumper beam, which is characterized by comprising a foam sandwich and an embedded part; the foam sandwich and the embedded part are coated with a carbon fiber sheet reinforced resin matrix composite; the invention also discloses a manufacturing method for the carbon fiber automobile bumper beam. Compared with the prior art, the carbon fiber automobile bumper beam disclosed by the invention has the advantages that (1) the weight is lightened: the aluminum alloy beam of the original structure is 2.66kg, and the aluminum alloy beam of the existing structure is 2.077kg; the weight is reduced by 21.92 percent; (2) the strength standard of the joint of a tow hook and an automobile body, i.e. the strength analysis standard of the joint of an SMTC4500010 tow hook and the automobile body, is met; (3) according to an automobile front/rear end protector of the GB17345-1988 standard, and RCAR (Research Council For Automobile Repairs) low speed crash tests, an exhaust structure, a power system and a suspension system are not damaged, and test results meet the requirements.

Description

technical field [0001] The invention relates to the technical field of preparing automobile parts from composite materials, in particular to a carbon fiber automobile buffer beam and a manufacturing method thereof. Background technique [0002] At present, the materials for making bumper beams of cars are generally metal materials (such as high-strength steel, aluminum alloy, magnesium alloy, etc.), and most bumpers use anti-collision steel beams. At present, with the development trend of lightweight, light metal and non-metal materials have also begun to be applied to automobile bumpers. For example, GMT material bumpers have been mass-assembled in Hyundai and Ford in South Korea and have good results. In recent years, the advantages of carbon fiber composite materials have been favored by people, such as good impact energy absorption. Carbon fiber composite materials are the most ideal substitute materials for automotive metal materials. The energy absorption rate in coll...
