Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a composite material grid cone shell wire laying and winding integrated molding device. Background technique [0002] The automatic wire laying technology combines the advantages of fiber winding and automatic tape laying technology. It can cut the tow at any time according to the change of the surface shape of the component, and continue to transport the tow when necessary. It is suitable for components with complex shapes such as concave curved surfaces, convex curved surfaces, and variable cross-sections. forming. Composite conical shell components formed by automatic wire laying technology abroad include American Minotaur rocket fairings, American space shuttle cryogenic tanks, and Atlas 5 launch vehicle load adapters. [0003] The development of automatic forming technology of composite material shell components in China is relatively late. At present...

AI Technical Summary

Problems solved by technology

The development of automatic forming technology of composite material shell components in China is relatively late. At present, it can only realize the automatic forming of composite material skin components with a cross-section near the cylinder, and the forming of tapered (curved surface) composite components with variable cross-section still adopts the method of manual forming.

For grid shell components, only wet winding is used to form the grid shell, but its shell thickness and layer angle are difficult to accurately design, while the dry winding is used to form the grid shell, only the ribs are wound. , the skin is formed by a combination of winding and manual layup, and the thickness of the layup is also difficult to control accurately
