Embodiment Construction

[0024] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

[0025] Such as Figure 1-3 Shown, the present invention is the preparation method of prepreg-vacuum assisted liquid forming article, and described preparation method comprises the following steps:

[0026] (1) Prepreg warming, cutting, and numbering: Take out the prepreg from the cold storage 6-8 hours before cutting, and return it to room temperature. After the prepreg is warmed up, import the prepreg cutting diagram into the cutting machine computer , cut the prepreg, write a sticky note according to the layer mark on the prepreg cutting diagram, and paste it on the cut prepreg, put the cut prepreg in a sealed bag and save it for later use;

[0027] (2) Heat setti...

Abstract

The invention provides a preparation method of a prepreg-vacuum auxiliary liquid forming workpiece. The preparation method comprises the first step of prepreg temperature returning, cutting and numbering, the second step of fabric heat shaping, cutting and numbering, the third step of prepreg and fabric laying, the fourth step of auxiliary material laying and made bag vacuum degree detection, thefifth step of glue injection and solidification, and the sixth step of workpiece die removal, cutting, polishing and paint spraying. The prepreg part and the liquid forming part are jointly solidified, the success rate of the workpiece is improved, and the workpiece cost is reduced. Meanwhile, the obtained prepreg-vacuum auxiliary liquid forming technological workpiece is good in rigidity, low inself weight, high in surface smoothness degree and low in workpiece porosity, and the outer surface size can be precisely controlled.

Description

technical field [0001] The invention relates to a preparation method of a prepreg-vacuum assisted liquid molding product. Background technique [0002] Advanced resin-based composite materials represented by carbon fiber composite materials have been widely used in aerospace and other fields because of their excellent comprehensive properties such as high specific modulus, high specific strength, designability, corrosion resistance, fatigue resistance, and easy integral molding. The amount and level of composite materials have become an important symbol of the advanced structure of aircraft. Composite materials have the characteristics of simultaneous completion of material molding and structural molding. For aircraft composite material structures, manufacturing technology is very critical, which not only determines product quality but also affects manufacturing costs. Contents of the invention [0003] The object of the present invention is to provide a prepreg-vacuum as...
