Compression molding method of carbon fiber automobile chassis part

Abstract

The invention discloses a compression molding method of a carbon fiber automobile chassis part. The method comprises the following steps: (1) an upper die and a lower die are respectively fixed on anupper sliding block and a lower workbench of oil pressure equipment, and an upper die cavity and a lower die cavity are respectively paved with two pieces of carbon fiber cloth, so that carbon fibersare completely adsorbed on the upper die cavity and the lower die cavity; (2) the upper die cavity and the lower die cavity are preheated; (3) the upper die is pushed to move towards the lower die byan upper sliding block of the oil pressure equipment, the upper die moves downwards to a fixed position under the action of an upper die guide plate and a lower die guide groove, a cavity gap definedby the upper die cavity and the lower die cavity is vacuumized, and a resin material is poured into the cavity gap defined by the upper die cavity and the lower die cavity; and (4) the upper die is pushed to move downwards through the upper sliding block of the oil pressure equipment to perform die-casting forming on the part. The process is simple, the part is formed in place in one step, the steps of plate shearing, stamping, forming and the like are omitted, the production cost is reduced, the mechanical performance of a product is greatly enhanced, and the density of workpieces with the same thickness is reduced.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber profile forming, and in particular relates to a press forming method for a carbon fiber automobile chassis part. Background technique [0002] At present, remarkable achievements have been made at home and abroad in the use of composite materials with excellent performance, light weight and high strength to realize the lightweight of automobiles. Carbon fiber composite materials have lightweight characteristics and sufficient strength and stiffness. The lightest material for main structures such as the chassis and chassis. At present, most of the conforming materials are made of steel, which has a limited weight reduction effect, and the manufacture of conforming plates is usually done by molding the parts first, and then pouring, the process is complicated and the cost is high. Contents of the invention [0003] In order to solve the above technical problems, the present invention provide...
