Membranous body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing membranous bodies made with super fibers lack sufficient strength and stability, particularly in applications requiring high resistance to creep, slippage, and puncture, as they do not effectively utilize the properties of super fibers and resin coatings.
Innovation Solution
A membranous body comprising a super fiber layer treated with deoiling and hydrophilic processes, intertwined or bound threads, and resin solvent layers containing super engineering plastics, enhancing adhesive strength and restraining thread fluctuations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional fiber and resin coating are used, then the membranous body can be manufactured, but the tensile strength and creep resistance are insufficient
Solution Approach 1:
The patent applies deoiling treatment and hydrophilic treatment to the super fiber layer to change its surface properties. These parameter changes in the fiber surface enable better adhesive interaction with the resin solvent, resulting in improved tensile strength (51 to 64 N/mm) and creep resistance while maintaining the lightweight characteristic
Solution Approach 2:
The patent creates a composite structure by coating resin solvent containing super engineering plastics onto the super fiber layer. This composite of super fiber and resin forms a integrated membranous body where the resin penetrates and bonds with the fiber, achieving high strength and reliability properties that neither material could achieve alone
2Strength
If resin coating is applied to enhance strength, then adhesive strength improves, but the membranous body becomes heavier
Solution Approach 1:
The patent uses deoiling and hydrophilic treatments to change the surface parameters of the super fiber layer, improving resin adhesion without requiring excessive resin coating. This enables achieving high tensile strength (51 to 64 N/mm) while controlling the mass within 45 to 55 g/m2
Solution Approach 2:
The resin solvent is selectively coated on the super fiber layer where it is most needed for structural integrity. The resin penetrates and bonds locally at the fiber-resin interface, providing adhesive strength where required without uniformly increasing the mass of the entire membranous body
