Fiber Bundle Curing Device for Filament Winding Tangling Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filament winding devices face issues with cut fibers tangling in guides due to uncured resin in fiber bundles during the winding process.
Innovation Solution
A fiber bundle processing device equipped with a curing device that applies heat to cure or semi-cure the resin at regular intervals along the feeding direction or perpendicularly to the fiber bundle, using rotating rollers or oscillating arms with integrated iron parts to prevent fiber separation and tangling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fiber bundle is guided into the liner without curing the resin, then the fiber bundle remains flexible and easy to guide, but the fibers can be separated and tangled in guides when cut
Solution Approach 1:
The curing device performs preliminary curing of the resin at regular intervals along the fiber bundle before the fibers are fully guided into the liner. This preliminary action strengthens the fibers at critical points, preventing separation and tangling when cuts occur during the guiding process, while still maintaining sufficient flexibility for operation.
2Reliability
If the resin is fully cured before winding, then fiber separation is prevented, but the fiber bundle loses flexibility and becomes difficult to guide
Solution Approach 1:
Instead of uniformly curing the entire fiber bundle, the curing device applies localized curing at regular intervals along the fiber bundle. This creates segments with different properties: cured sections provide fiber integrity and prevent tangling, while uncured sections maintain flexibility for guiding. This local differentiation resolves the contradiction between reliability and ease of operation.
3Reliability
If a curing device is added to the fiber bundle processing device, then cut fibers are prevented from tangling, but the device complexity increases
Solution Approach 1:
The curing device is designed to cure the resin continuously at regular intervals as the fiber bundle passes through, rather than requiring discrete stopping and curing operations. This continuous action integrates seamlessly with the existing winding process, minimizing additional complexity while maintaining fiber integrity throughout the guiding process.
