High-Pressure Tank Release Agent Layer Thickness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-pressure tanks, the mixing of resin from the reinforcing layer with the release agent layer can lead to reduced releasability between the liner and the reinforcing layer, causing sticking and hindering expansion and contraction due to temperature changes.
Innovation Solution
A high-pressure tank design with a release agent layer thickness equal to or smaller than the diameter of the reinforcing layer's fibers, preventing the mixing of resin and release agent and thus minimizing sticking between the liner and the reinforcing layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the release agent layer is made thicker to improve releasability between liner and reinforcing layer, then the liner can be released more easily, but the resin and release agent mix together causing sticking
Solution Approach 1:
The patent applies parameter changes by precisely controlling the thickness of the release agent layer to be equal to or smaller than the diameter of the fiber. This quantitative parameter adjustment resolves the contradiction by finding the optimal thickness value that prevents mixing while maintaining releasability. The release agent layer thickness is set within a specific range (1 μm to 6 μm) to achieve the desired effect.
2Object-generated harmful factors
If the release agent layer thickness is reduced to prevent mixing, then sticking is suppressed, but the releasability may be compromised
Solution Approach 1:
The patent resolves this contradiction by establishing a lower bound for the release agent layer thickness (1 μm to 6 μm). This parameter specification ensures that the layer is thin enough to prevent mixing of resin and release agent, yet thick enough to maintain sufficient releasability between the liner and reinforcing layer.
3Reliability
If more release agent is applied to improve releasability, then the liner releases more easily, but manufacturing cost increases
Solution Approach 1:
The patent addresses this contradiction by optimizing the release agent layer thickness to a specific range (1 μm to 6 μm) that is equal to or smaller than the fiber diameter. This parameter optimization achieves adequate releasability while minimizing the amount of release agent material required, thereby reducing manufacturing costs.
4Ease of manufacture
If the release agent layer is made thinner to reduce material cost, then manufacturing cost decreases, but releasability may be insufficient
Solution Approach 1:
The patent resolves this contradiction by establishing a minimum thickness threshold for the release agent layer (1 μm to 6 μm). This parameter specification ensures that even at reduced material thickness, the releasability function is maintained at an adequate level while achieving cost reduction through minimized material usage.

AI summary
A high-pressure tank includes a liner, a release agent layer disposed on a surface of the liner, and a reinforcing layer disposed on the release agent layer. The reinforcing layer includes a resin and a fiber. The thickness of the release agent layer is equal to or smaller than the diameter of the fiber of the reinforcing layer.
