Fibers-based flexible material and process of manufacturing such a material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Carbon, glass, and aramid fibers used in composite materials are not suitable for textile articles due to cracking and loss of cohesion during manipulation, limiting their use in flexible applications like clothing and bags.
Innovation Solution
A flexible material is created by impregnating a web of carbon, glass, or aramid fibers with a polymer binder containing a high concentration of plasticizing agents, which enhances cohesion and flexibility, allowing for easy manipulation and use in textile manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If carbon, glass, or aramid fibers are used in composite materials, then mechanical resistance is improved, but flexibility and ease of manipulation deteriorate due to cracking and loss of cohesion
Solution Approach 1:
The invention changes the chemical and physical parameters of the fiber matrix interface by introducing a polymer binder with specific plasticizers. The binder contains plasticizers at concentrations of 10-40% by weight, which fundamentally alters the mechanical properties of the composite, enabling flexibility while maintaining strength. This parameter change transforms the material from rigid and brittle to flexible and manipulable.
Solution Approach 2:
The invention creates a multi-component composite material system consisting of high-strength fibers (carbon, glass, or aramid), a polymer binder, and plasticizers. This composite structure combines the tensile strength of the fibers with the flexibility and cohesion-providing properties of the polymer-plasticizer matrix, resolving the contradiction between strength and flexibility.
2Stability of the object's composition
If fibers are organized in woven or unwoven arrangements, then structural integrity is improved, but flexibility and ease of manipulation deteriorate due to cracking during manipulation
Solution Approach 1:
The polymer binder acts as an intermediary substance between the fibers, coating and binding them together. This binder layer prevents direct fiber-to-fiber contact that would cause cracking during manipulation, while the plasticizers within the binder provide the necessary flexibility. The intermediary binder layer absorbs mechanical stresses during manipulation, preventing crack propagation.
