Bonding Preparation Patch for Resin Surface Imprinting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current airframe fabrication techniques require time-consuming machining to create a matte surface for bonding infrastructure to smooth resin-coated laminates, which is obstructed post-assembly and inefficient.
Innovation Solution
A bonding preparation patch with a foldable strip of resin porous material and a resin barrier, applied to the resin-treated surface to imprint a matte finish, enhancing bondability without further machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If machining is used to create a matte surface for bonding, then bondability is improved, but time consumption and manufacturing complexity increase
Solution Approach 1:
The matte surface pattern is applied to the resin-treated surface before bonding operations, eliminating the need for time-consuming post-assembly machining. The patterned surface is prepared in advance using a patch that imprints the desired texture directly onto the surface where bonding will occur.
Solution Approach 2:
The patent replaces mechanical machining operations with a chemical/physical imprinting process. Instead of using cutting tools to mechanically remove material and create a matte surface, a patch with a textured pattern is pressed onto the resin surface, transferring the pattern through resin absorption and mechanical pressure, thereby substituting complex mechanical systems with a simpler imprinting mechanism.

Solution Approach 2:
The patent changes the surface parameters of the resin-treated surface by imprinting a matte pattern. The patch material absorbs resin and transfers a textured pattern to the surface, altering the surface finish from smooth to matte, which significantly improves bondability without requiring complex machining equipment or processes.
3Strength
If post-assembly matte surface treatment is performed, then bondability is improved, but accessibility is reduced due to obstruction
Solution Approach 1:
The matte surface pattern is applied to the resin-treated surface before bonding operations, eliminating the need for post-assembly machining. The patterned surface is prepared in advance using a patch that imprints the desired texture directly onto the surface where bonding will occur.

AI summary
A bonding preparation patch for application to a resin treated surface is provided. The patch includes a strip having first and second portions, each of which has corresponding first and second sides. The strip is formed of resin porous material and is foldable such that the respective first sides of the first and second portions face each other. The patch further includes a resin barrier interposable between corresponding portions of the respective first sides and a tape including at least one adhesive side, which is securable relative to the first portion and disposable in contact with the second side of the second portion.
