Embodiment 1

[0012] A manufacturing process of fiber three-dimensional reinforced hollow composite material, the process firstly controls the temperature of the horizontal formwork to be 25°C to 35°C, sprays the resin for the first time on the horizontal formwork, lays the fiber three-dimensional woven fabric on the horizontal formwork, Let the resin infiltrate the fabric, then absorb the infiltrated fabric through a vacuum adsorption device, and then perform mechanical rolling. After the first rolling, spray the resin for the second time. After the injection is completed, repeat the mechanical rolling, and finally pass through the vacuum adsorption device. The fabric that has been soaked is adsorbed to adjust its height, and heated and solidified to obtain a fiber three-dimensional reinforced hollow composite material.

[0013] The process mainly includes the following features:

[0014] 1. Metering injection

[0015] According to the composite process flow, injection metering is complet...

Abstract

The invention relates to a process for manufacturing a fiber three dimensional reinforced hollow composite material. The process comprises: firstly, controlling the temperature of a horizontal mold plate to be between 25 and 35 DEG C, carrying out the first resin injection on the horizontal mold plate, and spreading a fiber three dimensional woven fabric on the horizontal mold plate so as to make the resin infiltrate the woven fabric; secondly, carrying out mechanical rolling, after the first rolling, carrying out the second resin injection, and repeating the mechanical rolling after the injection; and finally, sucking the infiltrated woven fabric through a vacuum sucking device to adjust the height of the woven fabric, and obtaining a product through heating, curing and molding. Compared with the prior art, the process is simple and favorable for environmental protection. The product has the advantages of high production efficiency, good precision of finished products, uniform resin infiltration and the like.

Description

technical field [0001] The invention relates to a fiber composite board, in particular to a manufacturing process of a fiber three-dimensional reinforced hollow composite material. Background technique [0002] Fiber three-dimensional reinforced hollow composite material is a new type of resin-based fiber three-dimensional reinforced three-dimensional composite material. The material is made of fiber three-dimensional woven fabric as the skeleton material, which is impregnated and cured with resin. The traditional technology for manufacturing this material is hand lay-up technology. The disadvantages of this technology are low production efficiency, poor precision of finished products, and poor uniformity of resin infiltration. Contents of the invention [0003] The object of the present invention is to provide a manufacturing process of fiber three-dimensional reinforced hollow composite material with high production efficiency, good precision of finished products and go...
