Description

technical field [0001] The invention belongs to the technical field of fiber winding, and in particular relates to a fiber winding device. Background technique [0002] After years of development, pressure vessels have been widely used in aerospace, medical and health, and daily life; with the continuous emergence of new materials and new processes, pressure vessels are developing towards lightweight and high strength. In the future, it will be developed towards a type IV container with a plastic inner liner and a fiber-wound outer surface as a reinforcement layer. The working pressure of Type IV container is higher, and because the fiber layer is used as the main pressure-bearing layer, the safety performance is higher. In different application fields, the size of the container is also different, which puts forward higher requirements for the versatility of the winding equipment. [0003] Filament winding is one of the important links in the pressure vessel forming proces...

AI Technical Summary

Problems solved by technology

At present, in the hoop winding process, single-bundle fiber hoop winding is mainly used. The winding efficiency of this process is low, and the current process cannot achieve continuous production, and there is manual intervention in the entire winding process.

[0005] The size of the inner liner of the pressure vessel is diversified, but the size of the inner liner that meets the multi-bundle fiber synchronous winding process is relatively single, which brings great limitations to the process

In the current multi-bundle fiber winding, multiple bundles of fibers (fiber number ≤ 5) are gathered into a large tow for winding, but the essence is still single-bundle winding; and during the winding process, it will cause fiber stacking, uneven winding, and winding process Medium fiber slippage, local stress concentration

At the same time, the degree of automation of single-bundle filament winding is low and the production efficiency is low
