Solution Overview
Problem
High-pressure gas storage containers require significant reinforcing members to achieve predetermined strengths, leading to increased weight, which is undesirable.
Innovation Solution
A method involving the irradiation of reinforcing fibers with plasma to enhance their adhesiveness with resin, allowing for a reduced number of reinforcing members to be wound around the liner while maintaining strength, utilizing a specific plasma irradiation process and resin impregnation to form reinforcing members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If many reinforcing members are wound around the liner to achieve predetermined strength, then the strength requirement is met, but the weight of the container increases
Solution Approach 1:
The patent applies plasma irradiation to change the surface parameters of reinforcing fibers, increasing their specific surface area and surface energy. This parameter change enhances resin adhesion to the fibers, allowing the reinforcing members to achieve higher strength efficiency. Consequently, fewer reinforcing members are needed to meet the predetermined strength requirements, thereby reducing the overall container weight while maintaining structural integrity
Solution Approach 2:
The patent creates a composite structure by impregnating plasma-treated reinforcing fibers with resin to form reinforcing members. The plasma treatment modifies the fiber surface to improve the interfacial bonding between the fiber and resin components. This optimized composite material achieves superior strength-to-weight ratio, enabling the container to meet strength requirements with reduced material quantity and lower overall weight
2Strength
If reinforcing fibers are impregnated with resin to form reinforcing members, then the structural strength is improved, but the adhesiveness between fibers and resin is initially insufficient
Solution Approach 1:
The patent utilizes plasma irradiation to change the surface parameters of reinforcing fibers, specifically increasing surface energy and creating active functional groups on the fiber surface. These parameter changes dramatically improve the chemical and physical adhesion between the fiber surface and resin matrix, ensuring reliable bonding and preventing interface failure under stress, thereby enhancing the overall reliability of the composite reinforcing members

AI summary
A method produces a high-pressure gas storage container that includes a liner and a reinforcing layer. The liner houses a high-pressure gas. The reinforcing layer is formed by winding a plurality of strip-shaped reinforcing members around an outer perimeter surface of the liner. The method includes irradiating plasma on at least a portion of the reinforcing fibers, and adjusting an irradiation intensity of the plasma such that an irradiation amount of the plasma with respect to the reinforcing fibers becomes constant in accordance with changes in a transport speed of the reinforcing fibers.
