Functionalised Reinforcing Component for Weldable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reinforcing components made from organosheets face issues with poor weldability due to matrix-poor edge layers and are prone to breakthroughs during handling or production, compromising system tightness, especially in applications like fuel tanks and battery housings.
Innovation Solution
A component design comprising a sheet-like reinforcing component with a higher stiffness and an attachment material of lower stiffness, connected to it, which can be welded and seals apertures, ensuring secure mounting and sealing of functional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If organosheets with high fiber content are used to reduce weight and increase performance, then mechanical properties are improved, but weldability deteriorates due to matrix-poor edge layers
Solution Approach 1:
A transition piece is introduced as an intermediary component between the organosheet and the component to be joined. This transition piece has a first bonding surface that bonds to the organosheet and a second bonding surface that bonds to the component. The transition piece acts as a mediator that overcomes the poor weldability of the organosheet edge layer by providing alternative bonding interfaces, thereby enabling reliable joining without directly welding to the problematic organosheet surface.
2Strength
If organosheets are used for structural components, then weight reduction and performance increase are achieved, but breakthroughs occur during handling or production compromising system tightness
Solution Approach 1:
The sealing function is segmented from the structural organosheet by introducing a separate sealing element or transition piece. This segmentation allows the organosheet to maintain its structural integrity and performance while the separate sealing component ensures system tightness by covering or sealing breakthroughs and defects in the organosheet, thereby maintaining reliability without compromising the weight reduction benefits.
