Composite Assembly Sealing With Molded Corner Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing methods for composite materials with reinforcing fibers and resin require separate sealing materials for the end surface, complicating the sealing process.
Innovation Solution
A sealing method involving a molded body placed at the corner between the front and end surfaces of a composite material, with a first sealing material applied to the molded body and extended to the second component, simplifying the sealing process by integrating the end surface sealing with the interface sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate sealing material is provided for the end surface of the composite material, then the end surface sealing is achieved, but the sealing process becomes complicated
Solution Approach 1:
The patent merges the end surface sealing function with the interface sealing function into a single sealing material application. The sealing material is applied to cover both the end surface of the composite material and the interface between components, eliminating the need for separate sealing operations and reducing process complexity while maintaining sealing reliability.
Solution Approach 2:
The sealing material serves multiple functions simultaneously: it seals the end surface of the composite material, seals the interface between components, and provides structural support. This multi-functional approach simplifies the overall sealing system by replacing multiple specialized sealing elements with a single universal sealing solution.
2Reliability
If multiple sealing materials are applied separately, then comprehensive sealing coverage is achieved, but the number of steps increases
Solution Approach 1:
The patent combines multiple sealing operations into a single application step. The sealing material is applied in one continuous operation to cover all required sealing areas including the end surface and interfaces, reducing the number of discrete steps from multiple separate applications to a single integrated application process.
Solution Approach 2:
The sealing material is designed and positioned to simultaneously cover multiple sealing requirements before the curing process begins. By pre-configuring the sealing material to extend across all necessary areas, the patent eliminates the need for sequential application steps and achieves comprehensive coverage in a single operation.

AI summary
The sealing method is for sealing between: a rear surface of a first component which is a composite material containing a reinforcing fiber and a resin; and a front surface of a second component facing the rear surface of the first component. The sealing method includes: a step (ST03) in which a molded body is placed at a corner between the front surface and an end surface of the first component, with a first sealing material interposed therebetween; and a step (ST06) in which a second sealing material is applied from the molded body up to the front surface of the second component.
