MANUFACTURING METHOD OF CARBON PRECURSOR FIBER FOR GAS DIFFUSION LAYER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18147870 titled 'MANUFACTURING METHOD OF CARBON PRECURSOR FIBER FOR GAS DIFFUSION LAYER
Simplified Explanation
The abstract describes a method of manufacturing a carbon precursor fiber for a gas diffusion layer with excellent tensile properties by controlling the cross-sectional shape of the carbon fiber.
- Polyacrylonitrile-based copolymer is prepared.
- Spinning products are obtained by spinning a spinning solution containing the copolymer in a coagulation bath.
- Carbon precursor fiber is obtained by drawing the spinning products through heat treatment.
- The coagulation bath consists of about 60% to 90% methanol and about 10% to 40% dimethylformamide.
Potential Applications
The technology can be applied in the manufacturing of gas diffusion layers for fuel cells, aerospace components, and other high-performance applications requiring materials with excellent tensile properties.
Problems Solved
This technology solves the problem of producing carbon precursor fibers with superior tensile properties, such as strength and modulus, by controlling the cross-sectional shape of the fibers during the manufacturing process.
Benefits
The method results in carbon precursor fibers with enhanced tensile properties, making them suitable for demanding applications where high strength and modulus are required.
Potential Commercial Applications
The technology can be commercialized in industries such as fuel cells, aerospace, automotive, and other sectors requiring high-performance materials for structural components.
Possible Prior Art
One possible prior art could be the traditional methods of manufacturing carbon fibers, which may not specifically focus on controlling the cross-sectional shape to enhance tensile properties.
Unanswered Questions
How does this method compare to existing techniques for manufacturing carbon fibers in terms of cost-effectiveness and scalability?
This article does not provide information on the cost-effectiveness and scalability of the proposed method compared to existing techniques.
What are the environmental implications of using methanol and dimethylformamide in the coagulation bath for manufacturing carbon precursor fibers?
The potential environmental impact of using methanol and dimethylformamide in the manufacturing process is not addressed in the article.
Original Abstract Submitted
Proposed is a method of manufacturing a carbon precursor fiber for a gas diffusion layer having excellent tensile properties (e.g., strength and modulus) by controlling the cross-sectional shape of carbon fiber. The method includes preparing a polyacrylonitrile-based copolymer, preparing spinning products by spinning a spinning solution containing the polyacrylonitrile-based copolymer in a coagulation bath, and obtaining a carbon precursor fiber by drawing the spinning products through heat treatment. The coagulation bath includes an amount of about 60% to 90% by volume of methanol and an amount of about 10% to 40% by volume of dimethylformamide based on the total volume of the coagulation bath.
