Translucent Flexible Sheet With Reinforcing Threads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing translucent or transparent flexible sheets made of polymethyl methacrylate (PMMA) or polycarbonate are fragile, burn easily, and have low impact resistance, while also being impermeable to gases and liquids.
Innovation Solution
A flexible sheet woven from translucent amorphous polymer ribbons with embedded reinforcing threads, such as glass, carbon, or aramid fibers, which provide enhanced mechanical strength and allow for permeability by creating an openwork structure, optionally using metal strips and a translucent coating for added reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible sheets are made of PMMA or PC with closed structure, then they provide good mechanical strength and transparency, but they are impermeable to gases or liquids
Solution Approach 1:
The patent applies porous materials by creating an openwork structure with regularly distributed openings in the flexible sheet. The sheet comprises a woven assembly of transparent polymer ribbons forming cells with openings that allow gas and liquid permeability while maintaining mechanical strength through the woven ribbon structure.
2Object-generated harmful factors
If woven veils are used to improve storage conditions, then they allow gas or liquid passage, but they are fragile and have low impact resistance
Solution Approach 1:
The patent applies composite materials by combining transparent amorphous polymer ribbons with reinforcing threads embedded within them. The reinforcing threads are distributed throughout the polymer material to significantly increase tensile strength and impact resistance while maintaining the openwork structure for permeability.
3Illumination intensity
If woven veils are used for transparency, then they allow light transmission, but they burn easily
Solution Approach 1:
The patent applies composite materials by embedding reinforcing threads within the transparent amorphous polymer ribbons. The combination provides fire resistance while maintaining light transmission properties of the transparent polymer material.
4Strength
If reinforcing threads are embedded in polymer ribbons, then tensile strength increases significantly, but the structure becomes more complex
Solution Approach 1:
The patent applies merging by integrating the reinforcing threads directly within the polymer ribbons during the forming process. The ribbons are created with embedded reinforcing threads already distributed throughout their structure, allowing the woven assembly to be formed as a unified structure without separate reinforcement steps.

AI summary
The invention relates to a flexible sheet (1) substantially translucent or transparent comprising a plurality of ribbons (2, 3, 4) formed, in whole or in part, from a translucent amorphous polymer material (9), said ribbons (2, 3, 4) being woven together and arranged both in a weft direction and in a warp direction, and characterized in that at least one group of parallel ribbons (2) arranged in the weft or warp direction comprises a textile core formed by reinforcing yarns (6).
