Forming method, structure and forming mold of 3D printing technology assisted carbon fiber component

Abstract

The invention discloses a forming method, structure and forming mold of a 3D printing technology assisted carbon fiber component, and belongs to the technical field of carbon fiber component forming processes. The forming method of the 3D printing technology assisted carbon fiber component comprises the following steps that a water soluble material is adopted, a digital mold is printed and formedthrough the 3D printing technology, carbon fiber prepreg is paved, a vacuum bag is adopted for coating, vacuumizing and heating curing are carried out for curing, cooling is carried out to room temperature, a water soluble inner mold is molten, products are formed, and machining is achieved. The problems that in the prior art, a metal mold needs to consider the demolding angle, the demolding effect of products is poor, products of complex structures cannot be formed, cost is high, and the production period is long are solved. The water soluble inner mold is adopted to be molten, low-temperature curing forming is achieved, no mold made of metal needs to be put in, products of complex products can be formed, the water soluble inner mold is formed through additive manufacturing, the filling rate can be selected during manufacturing, an environment-friendly material capable of being naturally degraded is adopted, and the production cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of carbon fiber component forming technology, in particular to a 3D printing technology-assisted forming method, structure and forming mold of a carbon fiber component. Background technique [0002] Carbon fiber refers to a high-strength and high-modulus fiber with a carbon content of more than 90%. Its high temperature resistance ranks first among all chemical fibers, and it is an excellent material for manufacturing high-tech equipment such as aerospace. Carbon fiber is mainly made of acrylic fiber and viscose fiber, which is oxidized and carbonized at high temperature. In the prior art, when processing carbon fiber components, the bag press process is mainly used. As a thermosetting molding method for composite materials, the bag press process refers to the method of removing trapped air, voids and excess resin in the composite structure by suction. [0003] The bag pressing process is divided into three...
