Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current composite materials reinforced with natural organic fibers face challenges in reproducibility of mechanical characteristics due to poor fiber orientation and matrix migration during impregnation, leading to inconsistent performance in applications such as the transport, sports, and construction industries.
Innovation Solution
A hybrid textile comprising co-woven, co-braided, or co-knitted natural organic fibers and inorganic fibers, such as glass, basalt, or carbon fibers, which are treated to enhance fiber/matrix adherence and mechanical properties, resulting in a lightweight composite with improved reproducibility and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If natural organic fibers are used as reinforcement, then weight reduction is achieved, but mechanical performance consistency deteriorates due to poor fiber orientation and matrix migration
Solution Approach 1:
The patent applies composite materials by combining natural organic fibers with synthetic fibers (glass, carbon, or aramid) to create a hybrid reinforcement textile. This composite approach allows the natural fibers to provide weight reduction while the synthetic fibers ensure consistent mechanical performance and proper fiber orientation, thereby resolving the contradiction between weight reduction and mechanical performance consistency.
Solution Approach 2:
The patent applies local quality by creating regions with different fiber compositions within the textile reinforcement. The textile includes both natural organic fibers and synthetic fibers in specific arrangements, allowing different areas to contribute different properties: natural fibers for weight reduction and synthetic fibers for structural consistency and orientation control, thus resolving the contradiction locally across the reinforcement structure.
2Weight of moving object
If natural organic fibers are used as reinforcement, then weight reduction is achieved, but fiber orientation deteriorates due to twisting and weave path variations
Solution Approach 1:
The patent uses composite materials by integrating synthetic fibers with natural organic fibers in a hybrid textile. The synthetic fibers provide straight, consistent orientations that maintain manufacturing precision, while the natural fibers contribute weight reduction. This composite structure resolves the contradiction between weight reduction and fiber orientation precision.
Solution Approach 2:
The patent applies parameter changes by modifying the physical and chemical properties of the natural fibers through treatment processes. These treatments alter the fiber surface characteristics and mechanical properties, enabling better alignment and orientation control during textile manufacturing, thereby maintaining manufacturing precision while preserving the weight advantage of natural fibers.
3Weight of moving object
If natural organic fibers are used as reinforcement, then weight reduction is achieved, but matrix impregnation deteriorates due to matrix migration within warp yarns
Solution Approach 1:
The patent applies composite materials by combining natural organic fibers with synthetic fibers in a hybrid textile structure. The synthetic fibers provide a stable framework that prevents matrix migration during impregnation, while the natural fibers maintain weight reduction benefits. This composite approach resolves the contradiction between weight reduction and ease of manufacture regarding matrix impregnation.
Solution Approach 2:
The patent applies parameter changes by treating the natural organic fibers to modify their surface properties and dimensional stability. These treatments prevent excessive swelling or shrinkage during matrix impregnation, eliminating matrix migration issues while preserving the weight advantage of natural fibers, thus resolving the contradiction between weight reduction and ease of manufacture.
