Coated composite component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coatings for composite components are difficult to remove cleanly before further processing, leading to contamination risks and challenges in inspecting coating quality, especially during storage and transportation, and can leave residues that affect bonding or welding processes.
Innovation Solution
A coated composite component design featuring a fluorine-containing film or woven fabric attached to a tear-off fabric, where the fluorine-containing material is securely fixed to the edges of the composite component, ensuring easy detachment of the coating without contamination, and allowing for thorough cleaning and inspection of the surface before further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fluorine-containing film or woven fabric is applied to the composite component, then the surface is protected against contamination, but the coating can detach too easily during transportation and storage
Solution Approach 1:
The coating system is divided into two distinct layers: a fluorine-containing film that provides surface protection and contamination resistance, and a tear-off fabric that provides mechanical stability and secure attachment during transportation and storage. This segmentation allows each layer to perform its specific function optimally without compromising the other.
Solution Approach 2:
The tear-off fabric acts as an intermediary carrier that temporarily holds the fluorine-containing film in place on the composite component. This intermediary structure provides the necessary mechanical stability during storage and transport, then can be easily removed to leave the fluorine-containing film intact on the component surface.
2Ease of operation
If a conventional tear-off fabric is used for coating removal, then the coating can be removed, but residues from separating agents remain on the surface affecting bonding or welding
Solution Approach 1:
The tear-off fabric is designed as a disposable, single-use component that is intentionally sacrificed during the removal process. By using a dedicated tear-off fabric rather than relying on the fluorine-containing film itself as the removable layer, the system ensures that any separating agents or residues are confined to the disposable fabric rather than remaining on the component surface.
Solution Approach 2:
The harmful separating agents and residues are extracted and isolated in the tear-off fabric layer, which is then completely removed from the system. This extraction process separates the contamination-generating material from the component surface, ensuring that the fluorine-containing film and component remain free of residues that would interfere with bonding or welding operations.
3Difficulty of detecting and measuring
If the fluorine-containing film surface area is reduced, then cleaning and inspection become easier, but the protective coverage is insufficient
Solution Approach 1:
The fluorine-containing film is strategically positioned and sized to provide protection only at the specific locations on the composite component where contamination protection is most critical. This local quality approach ensures adequate protective coverage at key areas while maintaining manageable dimensions that facilitate cleaning and inspection operations.
