Embodiment 1

[0045] A light carbon fiber carrying case integral molding process, comprising the following steps:

[0046] (1) Combined assembly of the mold

[0047] The mold includes 4 box body molds and 2 box cover molds, and the 4 box body molds are molded into box molds with openings at both ends, and the inside and outside of the box mold joints are sealed with adhesive tape;

[0048] (2) Process layup

[0049] First lay ±45° carbon fiber, 0 / 90° carbon fiber, carbon fiber-aramid mixed fabric, carbon fiber-aramid mixed fabric, ±45° carbon fiber, 0 / 90° carbon fiber, demoulding on the inner wall of the box mold in sequence Cloth; pre-buried boards are embedded in the fiber layer at the four corners of the cabinet, and slots are drilled on the buried boards;

[0050] After the box mold is laid, clean and wax the surface of the box cover mold, and lay ±45° carbon fiber, 0 / 90° carbon fiber, carbon fiber-aramid blended cloth, carbon fiber-aramid blended cloth, ±45° carbon fiber, 0 / 90° carb...

Abstract

The invention relates to an integral molding process for a light portable carbon fiber box. The integral molding process comprises the following steps: (1) combining and assembling a mould; (2), laying up; (3) arranging a guide net and a spiral net; (4) sealing the mould; and (5) performing a guide process. Compared with the prior art, the integral molding process has the advantages that aramid fibers and carbon fibers are mixed and laid up, so that the mechanical performances including toughness, impact performance, strength, rigidity and the like are comprehensively improved when the box body is kept light; through grooves and small through holes in a buried plate, resin ribs can be dispersed more quickly; the guide net and the spiral tube are arranged, and the guide process is set, so that the resin penetrates layer by layer in a transverse direction and a longitudinal direction of lay-up layers, and the porosity is reduced by connecting the lay-up layers more tightly through the resin; high-strength and low-temperature curing epoxy resin can be quickly cured at low temperature, so that the molding time is shortened, the operation environment is improved, the process flow is simplified, and the operation environment is improved.

Description

technical field [0001] The invention relates to a forming process of a carrying case, in particular to an integral forming process of a light carbon fiber carrying case. Background technique [0002] At present, hand lay-up is the most widely used composite molding process for small parts. [0003] Hand lay-up molding: first paint the resin mixture containing curing agent on the mold, then spread the fiber fabric cut according to the requirements on it, squeeze the fabric with tools, remove air bubbles to make the impregnation even, and then paint the resin mixture And shop the second layer of fiber, repeat the above process to reach the desired thickness. Finally, it is heated and solidified to form, and the product is demoulded to obtain the product. [0004] For the movable carrying case with complex structure, the existing problems mainly contain the following points: [0005] 1. Defects of hand lay-up process: [0006] a. The resin content in the fiber is large, and...
