Abstract

The invention relates to a combination mold and working method for automatic laying of composite materials. The combination mold includes a main mold tire, a flexible insert mold, a stopper and a rigid insert mold, and the main mold tire is used for forming a composite material blank , when the prepreg used to form the composite material blank is laid on the surface of the main mold tire, the flexible insert mold is a rigid airbag structure, which is set on the edge profile of the main mold tire, and the flexible insert mold There is an air inlet valve on the top, and the stopper is set on the side end surface of the main mold tire, and the stopper is at least higher than the bottom surface of the flexible insert mould, which is used to limit it. When the prepreg laying is completed, the rigid insert The block mold replaces the flexible insert mold and is set on the edge profile of the main mold tire, and the upper surface profile of the rigid insert mold matches the surface shape of the composite material blank, and the working surface of the upper surface of the flexible insert mold The curvature is less than the curvature of the working face of the upper surface of the rigid insert mold.

Description

technical field [0001] The invention relates to the technical field of composite material parts manufacturing, in particular to a composite mold and working method for automatic laying of composite materials. Background technique [0002] Resin-based composite materials are widely used in aerospace, high-speed rail and other military or civilian fields. The application structure is becoming more and more complex, and the requirements for manufacturing quality and manufacturing efficiency are also getting higher and higher. At present, the manufacture of resin-based composite parts is still mainly manual, but with the development of automation and intelligent technology, more and more automated manufacturing technologies are applied to the field of composite material molding manufacturing, and automatic wire laying based on prepreg The manufacturing of composite material parts is an automated manufacturing technology that has developed rapidly in recent years. This technology...
