Description

Technical Field

[0001] This invention relates to the field of mesh reinforcement compartment technology, specifically providing a waverider mesh reinforcement compartment mold and a method for preparing the reinforcement compartment. Background Technology

[0002] In recent years, the composite materials industry has developed rapidly, mainly due to the urgent need for lightweight structures in industrial sectors such as aerospace and high-speed rail. Composite material mesh-reinforced compartment structures are widely used in various compartments such as rocket body structures and missile body structures due to their high strength, high specific modulus, low cost, short production cycle, and high stability.

[0003] However, with the continuous development of the composite materials industry, the size of the modules is constantly increasing, the materials are constantly being updated, and the structures are becoming more complex, which places higher demands on the mold design and molding manufacturing process of composite mesh reinforcement modules. At present, domestic composite material related units have achieved relatively mature technology in the field of regular-shaped composite material modules, but research on large-size waverider mesh reinforcement modules is relatively limited, and there are many problems, making it difficult to guarantee product quality.

[0004] As a type of waverider structure composite material mesh reinforcement section, the mold design, longitudinal ring reinforcement prepreg laying, product size control and curing process are the key targets that need to be tackled at present. Summary of the Invention

[0013] A method for manufacturing a waverider mesh reinforcement section, utilizing the aforementioned waverider mesh reinforcement section mold, includes the following steps: S1: Prepare carbon fiber prepreg and cut it into pieces.

[0014] S2: T-shaped ring frames are laid on the segmented male mold using carbon fiber prepreg.

[0024] 2) The pressure mold is a one-piece structure made of P20 mold steel, which has high overall rigidity and solves the deformation problem during the molding and mold closing process. The pressure mold and the female mold adopt a conical structure, which allows the pressure mold to move only along the axial direction of the female mold, ensuring the uniformity of product thickness and the accuracy of the outer surface contour dimensions.

[0025] 3) The present invention ensures the integrity and continuity of the longitudinal ring ribs by using uniformly distributed first and second reinforcing ribs and a pressure mold for pre-pressing, thus avoiding damage caused by cutting the first and second reinforcing ribs.

[0026] 4) The process of the present invention is simple, has good integrity, and does not damage the performance of the first reinforcing rib and the second reinforcing rib. Attached Figure Description
