Problems solved by technology

[0002] Compared with traditional composite materials, the composite curing process of resin-based three-dimensional braided composite parts is different. For good three-dimensional braided preforms, the composite curing process used in traditional composite materials cannot ensure that the preforms are saturated with resin

Embodiment Construction

[0016] In order to further understand the advantages of the present invention, the efficacy of the present invention will be illustrated through specific examples below.

[0017] as attached figure 1 Shown: a resin-based three-dimensional braided composite material molding process, including the following steps:

[0018] (1) Preparation of prefabricated parts: Before loading the mould, place the three-dimensional woven prefabricated part in an oven to heat and dry to remove the moisture in it, so as to prevent the moisture in the prefabricated part from affecting the effect of the release agent, and at the same time avoid the internal Bubbles are generated, the oven temperature is 120°C, and the time is 2 to 3 hours. After drying, take out the preform and cut it into the required size, and then weigh it;

[0019] (2) Mold preparation: Before loading the mold, the mold must be cleaned. Use blades, sandpaper, acetone, etc. to remove impurities such as residual resin and rust sp...

Abstract

The invention relates to a forming process of a resin-based three-dimensional braided composite material. The forming process comprises the following steps of (1) preparing prefabricated elements; (2) preparing a mold; (3), assembling the mold; (4) preparing resin; (5) injecting glue; (6) curing; and (7) opening the mold. The forming process of the resin-based three-dimensional braided composite material has the characteristics of low energy consumption, less environment pollution, accurate product size, good surface quality, high stability, high finished product rate, and capability of forming products with complex shapes. The mold manufacture and material selection are high in flexibility, and complex constructional elements with favorable surface quality and high dimension accuracy can be manufactured; the fiber volume of the composite material is high; the composite material product is low in porosity; the formed three-dimensional braided composite material generally is not required to be subjected to mechanical processing, and therefore, not only is the additional expense reduced, but also the fiber damage caused by post processing is also prevented. The forming process of the resin-based three-dimensional braided composite material is widely applied to the fields of aerospace, national defense, war industry, traffic transportation, buildings, civil industry and the like.

Description

technical field [0001] The invention belongs to the technical field of material forming, and in particular relates to a resin-based three-dimensional braided composite material forming process. Background technique [0002] Compared with traditional composite materials, the composite curing process of resin-based three-dimensional braided composite parts is different. As far as good three-dimensional braided preforms are concerned, the composite curing process adopted by traditional composite materials cannot ensure that the preforms are saturated with resin. Therefore, the molding process of resin-based three-dimensional braided composites is a difficult problem to be solved. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a resin-based three-dimensional braided composite material molding process, which has low energy consumption, low environmental pollution, accurate product size, good surface quality, h...
