Composite Backing Layer Peel Starter for Damage-Free Edge Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The removal of backing layers from composite materials is time-consuming and can undesirably affect the composite material, disrupting its mechanical properties.
Innovation Solution
A composite backing layer peel starter comprising a rigid hammer and a striker with a polymeric material contact surface is used to apply an impact and lifting force to create a free edge of the backing layer, allowing for efficient automated removal without disturbing the composite ply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional methods are used to remove the backing layer, then the backing layer can be removed, but the process takes an undesirable amount of time and causes undesirable effects on the composite material
Solution Approach 1:
The polymeric material contact surface is applied to the backing layer corner before removal begins, creating initial adhesion that enables controlled peeling. This preliminary action prepares the backing layer for efficient removal by establishing a grip point at the corner, allowing the process to start smoothly without damaging the composite material.
2Productivity
If the backing layer is removed efficiently, then productivity improves, but traditional methods cause undesirable effects on the composite material
Solution Approach 1:
The polymeric material contact surface is specifically designed to interact only with the backing layer corner, applying localized adhesion forces at the peeling initiation point. This local quality ensures that removal forces are concentrated at the corner rather than distributed across the entire composite material, enabling efficient removal while preserving the integrity of the composite ply.
Solution Approach 2:
The polymeric material contact surface acts as an intermediary between the striker and the backing layer. It transfers the impact force from the striker to the backing layer corner, creating controlled adhesion that enables smooth peeling. This intermediary mechanism allows efficient removal while preventing direct mechanical damage to the composite material.
3Ease of operation
If an impact force is applied to create a free edge, then the backing layer can be removed more efficiently, but the force application must be controlled to avoid damage
Solution Approach 1:
The polymeric material contact surface changes the physical parameters of the interaction between the striker and backing layer. It provides controlled adhesion strength and flexibility, allowing the impact force to be absorbed and distributed in a way that creates a free edge without exceeding the damage threshold of the composite material. The polymeric material's mechanical properties are optimized to balance peeling ease with composite protection.
