Device and method for manufacturing carbon fiber reinforced composite construction member

Abstract

The invention discloses a device and method for manufacturing a carbon fiber reinforced composite construction member, belonging to the fields of composite molding and processing. In the invention, through wet-state blanking technologies such as trimming, punching, parting off and the like after resin penetration molding and before solidifying, an outer contour and an inner bore are processed while the carbon fiber reinforced composite construction member is molded; and therefore, the device and method for manufacturing the carbon fiber reinforced composite have the advantages of effectively reducing or avoiding the follow-up milling and drilling processing requirements on a carbon fiber reinforced composite workpiece which is difficult to process in the conventional molding process, improving the molding efficiency and the workpiece surface quality and reducing the device requirements and the manufacturing cost, and is particularly suitable for the manufacturing of large size carbon fiber reinforced composite construction members.

Description

technical field [0001] The invention belongs to the field of composite material molding and processing, and relates to a carbon fiber reinforced composite component manufacturing device and method, which are suitable for the integrated manufacturing of molding and processing of carbon fiber reinforced composite (CFRP) covering parts and structural parts. Background technique [0002] In recent years, with the rise of crude oil prices and the increasingly urgent requirements for environmental protection, the use of various carbon fiber reinforced materials to reduce the weight of the structure and improve fuel economy also has broad applications in civil industries such as automobiles and ships other than aerospace. Application prospect. The specific gravity of carbon fiber reinforced material (CFRP) is less than 1 / 4 of that of steel, but its tensile strength is about 7.9 times that of steel, and its tensile elastic modulus is also higher than that of steel. Compared with met...

AI Technical Summary

Problems solved by technology

However, carbon fiber reinforced materials (CFRP) are typical difficult-to-machine materials with high hardness and high rigidity. Large force, high cutting temperature, severe tool wear, and the quality of the machined surface is affected by problems such as carbon fiber tearing and chip curling during the cutting process [a ceramic drill bit for high-speed drilling of composite materials, application number 200810134628; overall hard Quality alloy fish scale milling cutter, application number 200910013142]
