These issues are characteristic of continuous fibre preforms and the inextensibility of the fibres. HiPerDiF (High Performance Discontinuous Fibre) technology is a novel manufacturing technique to produce high-performance, aligned discontinuous fibre pre-preg materials. This study investigates the forming characteristics of prepreg manufactured using the HiPerDiF method, highlighting its viability for complex part manufacture where mould conformity is critical. Additionally, a previously developed finite element (FE) model, able to predict the behaviour discontinuous fibre preforms during double diaphragm forming (DDF), was used to obtain insights into the experimentally observed material deformation. The results demonstrated the advantage of the enhanced formability of the HiPerDiF preform, owing to its stretchability in the double-diaphragm vacuum forming process.

The effectiveness of LF is governed by three primary mechanisms Temperature Gradient Mechanism (TGM), Buckling Mechanism (BM), and Upsetting Mechanism (UM)) which are influenced by process parameters such as laser power, scanning speed, beam diameter, and material properties. This review presents a comprehensive overview of recent advancements in LF, beginning with an analysis of the governing deformation mechanisms and their role in achieving precision and control. It then explores critical microstructural changes including grain refinement, phase transformations, and heat-affected zones (HAZ) that directly impact material behavior and performance. Building upon these foundational aspects, the article highlights current innovations in LF process enhancement through machine learning (ML)-based optimization, real-time thermal feedback, and adaptive control strategies. Challenges such as edge effects, residual stresses, and process repeatability are discussed, along with mitigation approaches Like forced cooling and adaptive scanning. Experimental findings show that forced cooling can increase the bending angle by up to 35.2% and improve energy efficiency by 22.14%.

The study found that increasing the laser power from 4 kW to 6 kW significantly raises the Keyhole collapse frequency and porosity. This is attributed to the increased recoil pressure and melt pool depth, which hinder bubble escape. Increasing the welding speed from 0.008 m/s to 0.05 m/s reduces porosity by enhancing the melt pool’s kinetic energy, which offsets interfacial forces, and by lowering heat input to Maintain Keyhole stability. Welding current exhibits a nonlinear effect on porosity, In the range of 100 A to 150 A, electromagnetic forces enhance melt pool stability and extend solidification time, promoting bubble escape. However, when the current increases from 150 A to 225 A, excessive heat input leads to local overheating and intensifies Keyhole instability.

The objective was to identify key factors influencing crown formation and develop control strategies to ensure product quality and consistency. A finite element model was constructed to simulate the fourteen-stand rolling mill system, integrating static and dynamic analyses to evaluate the rolled crown value under various process parameters. The simulation results were validated against actual rolling data, confirming the model’s accuracy. Factors affecting crown formation were identified through simulation and analysis, including reduction per pass, friction coefficient, lateral displacement of intermediate rolls, strip entry position, input strip crown, material strength, strip width, and entry/exit tension. Empirical formulas were derived to predict crown values based on these parameters, providing a scientific basis for process optimization. Optimization recommendations included adjusting intermediate roller lateral displacement, annealing before the final rolling pass, selecting narrow strip, implementing progressive reduction per pass and controlling strip entry position. An experimental investigation validated the simulation findings, Maintaining thickness tolerance within a stringent standard of less than 1 micron, demonstrating the feasibility of ultra-high precision rolling for silver strips. In conclusion, this study significantly contributes to the understanding and control of crown formation in ultra-thin silver strip rolling, offering a scientific basis for optimizing the rolling process and improving product quality.

However, even if hydrogen offers a promising eco-friendly solution for the energy transition, several issues related to its storage and delivery need to be resolved in order to predict its wide use in both stationary and automotive applications. Hydrogen has the lowest volumetric energy density of all commonly used fuels (0.01079 MJ/L at atmospheric pressure). However, compression emerges as a direct and effective solution to this issue, with high pressures capable of significantly enhancing hydrogen's energy density, thereby augmenting its practicality. The energy densities achievable under high pressure are indeed impressive, making hydrogen highly practical. In mobile applications, hydrogen is typically stored as a gas in high-pressure composite overwrapped pressure vessels (COPVs). To achieve optimal functionality for high-pressure applications, two fundamental objectives must be met: ensuring exceptional structural integrity and maximizing gas impermeability. The commercialization of these vessels therefore presents a range of engineering challenges, including the development of advanced manufacturing techniques, the enhancement of structural properties, and the selection of appropriate materials, among others. The trend towards high-pressure hydrogen storage tanks is characterized by low cost, lightweight, and favorable safety performance. Consequently, the development of an efficient, sustainable, and safe high-pressure hydrogen storage method is a crucial focus of recent research, aiming to optimize hydrogen's utility in various applications.
