Summary
Optimizing towpreg dry filament winding for hydrogen storage vessels enhances efficiency and performance. This advanced manufacturing method significantly reduces vessel mass and boosts hydrogen storage capacity.
Area of Science:
- Materials Science
- Chemical Engineering
- Mechanical Engineering
Background:
- Hydrogen storage vessels are crucial for hydrogen energy systems.
- Next-generation Type IV vessel designs require improved manufacturing efficiency and structural performance.
- Towpreg dry filament winding offers advantages over conventional wet filament winding, including higher efficiency and reduced environmental impact.
Purpose of the Study:
- To systematically optimize key process parameters for towpreg dry filament winding.
- To enhance the tensile strength and interlaminar shear strength of hydrogen storage vessels.
- To improve the manufacturing efficiency and structural performance of Type IV hydrogen storage vessels.
Main Methods:
- Response surface methodology (RSM) was used to develop a regression model correlating process variables with mechanical properties.
- Multi-objective optimization was performed using the non-dominated sorting genetic algorithm II (NSGA-II).
- The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method was employed for final parameter selection.
Main Results:
- Heating temperature was found to be the primary factor influencing shear strength, while winding tension mainly governed tensile strength.
- An optimal parameter combination (79 N, 360 °C, 11 m/min) achieved high tensile (2462.2 MPa) and shear (64.4 MPa) strengths with prediction errors under 0.5%.
- A 9 L Type IV vessel produced using these parameters exhibited 15.4% lower mass and 17% higher gravimetric hydrogen storage efficiency compared to wet wound vessels.
Conclusions:
- The optimized towpreg dry filament winding process significantly improves the mechanical properties and efficiency of Type IV hydrogen storage vessels.
- This manufacturing approach offers a viable solution for developing lighter and more efficient hydrogen storage systems.
- The study demonstrates the effectiveness of RSM, NSGA-II, and TOPSIS in optimizing complex manufacturing processes for advanced materials.

01:23Design of Prismatic Beams for Bending
661
The design of prismatic beams, structural elements with a uniform cross-section, focuses on ensuring safety and structural integrity under load. The design process begins by determining the allowable stress, either from material properties tables, or by dividing the material's ultimate strength by a safety factor. This safety factor is essential for accommodating uncertainties, and varies depending on the material—timber, steel, or concrete—with each having unique strength and...

Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...

638
In designing structural elements and machine parts using ductile materials, it is crucial to ensure that these components withstand applied stresses without yielding. Yielding is initially determined through a tensile test, which evaluates the material's response to uniaxial stress. However, tensile stress is insufficient when components face biaxial or plane stress conditions This condition requires advanced criteria to predict failure.

637
In the study of elastoplastic members subjected to bending moments, understanding the loading and unloading phases is crucial for assessing material behavior and structural integrity. During the loading phase, as the bending moment increases, the material initially responds elastically, adhering to Hooke's Law, where stress is directly proportional to strain. When the load exceeds the yield strength, plastic deformation occurs, resulting in permanent strain and deformation that remains even...

In analyzing a structural member composed of two different materials with identical cross-sectional areas, it is crucial to understand how their distinct elastic properties affect the member's response under load. The analysis involves assessing stress and strain distributions using the transformed section concept, which accounts for variations in material properties.
