Composite Sheet for Bonding Flat Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite sheets fail to permanently attach glass panes and moisture-sensitive components like mirrors to hard surfaces due to material changes from temperature fluctuations, and existing on-site application methods are cumbersome and unsuitable for all types of components.
Innovation Solution
A composite web with a plastic film, fabric layer, and non-woven cover layer, containing a mineral filler with a plastic adhesive, laminated without air cushions, and featuring a self-adhesive layer for easy application, allowing for secure and permanent attachment of flat components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If known composite sheets are used to attach glass panes to hard surfaces, then the attachment process is simplified, but the attachment is not permanent and glass panes become detached due to temperature fluctuations
Solution Approach 1:
The patent applies a composite material structure consisting of a plastic film base layer, a fabric layer with mineral filler and plastic adhesive, and a non-woven cover layer. This multi-layer composite construction combines the flexibility and adhesion of plastic materials with the structural stability and temperature resistance of mineral-filled fabric, creating a bonding agent that maintains permanent attachment across temperature fluctuations while remaining easy to apply.
2Reliability
If composite mortar is used to bond glass panes to substrates, then permanent attachment is achieved, but the application process becomes complicated and time-consuming
Solution Approach 1:
The patent incorporates plastic adhesive already bound within the fabric layer during manufacturing, rather than requiring application of separate adhesive materials on-site. The mineral filler and adhesive are pre-mixed and integrated into the fabric structure, allowing the composite sheet to be applied as a complete bonding solution without complex mixing, application, and curing procedures required by traditional composite mortars.
3Object-affected harmful factors
If intermediate layers with water vapor permeability are used for sealing, then moisture protection is provided, but moisture-sensitive components such as mirrors cannot be protected
Solution Approach 1:
The patent employs a non-woven cover layer made of plastic fibers on the side facing moisture-sensitive components, providing a moisture barrier specifically where needed. The plastic adhesive bound in the fabric layer also contributes to moisture resistance. This localized moisture protection strategy allows the composite sheet to protect sensitive components like mirrors while still permitting breathability in other areas through the fabric's structure.
