Embodiment 1

[0012] A manufacturing process of a fiber three-dimensional reinforced hollow composite material. The process first controls the temperature of a horizontal template at 25°C to 35°C, sprays resin on the horizontal template for the first time, and lays the fiber three-dimensional woven fabric on the horizontal template. The resin is infiltrated into the fabric, and then the infiltrated fabric is absorbed by a vacuum suction device, and then mechanically rolled. After the first rolling is completed, the resin is sprayed for a second time. After the spraying is completed, the mechanical rolling is repeated, and finally the vacuum suction device is used. Adsorb the wetted fabric to adjust its height, and heat and solidify to form a three-dimensional fiber reinforced hollow composite material.

[0013] The process mainly includes the following characteristics:

[0014] 1. Metered injection

[0015] According to the composite process, the injection metering is completed in two times. Fir...

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 makethe 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. Comparedwith 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 uses three-dimensional fiber woven fabric as the framework material, and is made by resin infiltration and curing. The traditional process technology for manufacturing the material is hand lay-up technology. The disadvantages of this process technology are low production efficiency, poor precision of finished products, and poor resin infiltration uniformity. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art and provide a manufacturing process of a fiber three-dimensional reinforced hollow composite material with high pro...
