A method for manufacturing fully adaptive support tooling for soft mold auxiliary support

Abstract

The invention discloses a method for manufacturing a fully adaptable supporting tool for soft mold auxiliary support. Based on the soft film of a composite material product and its tooling, the profile is leveled by filling materials, and then the supporting tooling is laid and compounded. The material prepreg is formed by hot pressing in an autoclave, and after demoulding, it forms an overall fully adaptable support tooling. The support tooling manufactured by the method of the present invention has good strength, high rigidity, good use effect, and avoids the risk of wrinkles or buckling caused by web paving; and it is an integral support without matching gaps, and can be matched with multiple batches of soft molds, The state is stable; combined with the soft mold, the operation is simple and the matching is good, and the manufacturing accuracy and quality of the product are guaranteed; in addition, the composite support tooling manufactured by the method of the present invention can be reused, and at the same time, prepreg can be used for maintenance, and remanufacturing is also possible. It is more convenient, and effectively reduces the production cost and the manufacturing cycle.

Description

technical field [0001] The invention relates to a manufacturing method of a fully adaptable support tool used for auxiliary support of a soft mold. Background technique [0002] Resin-based carbon fiber composites have superior properties such as high specific strength and specific stiffness, strong designability, good fatigue fracture resistance, corrosion resistance, and good dimensional stability. They are currently widely used in aviation, aerospace, transportation and other fields. High performance structural material. Among a variety of carbon fiber composite material forming processes, the autoclave process has uniform forming temperature and pressure, and has good adaptability to parts of different materials, shapes, sizes and structures, so it has become a research and manufacturing aerospace high-quality composite material. One of the main process methods of material components. [0003] With the increasing requirements for the strength and stiffness of composite...

Problems solved by technology

However, the support structure of lightweight foam materials is weak, and the soft mold is prone to collapse during the laying process, the laying surface is uneven, and the web and flanging areas are prone to fiber folds or buckling; and the foam support is a split component. The quantity is large and the shape is similar, and the combination process with the soft mold takes too long

In addition, whether it is a metal support or a lightweight foam support, there is a large fit gap and poor state stability when combined, which affects the manufacturing accuracy of the product and the molding quality of the product
