Abstract Tungsten-copper laminated composites are promising materials for high heat-flux applications, but their performance is often limited by interfacial instability caused by the thermal-mechanical mismatch between tungsten and copper. In this study, W/W-30Cu/CuCrZr three-layer composites are fabricated by high-pressure torsion (HPT) processing. Experimental characterization and molecular dynamics (MD) simulations are used to systematically investigate the influence of HPT process parameters and intermediate-layer composition on the evolution of microstructure and mechanical properties. HPT processing significantly refines the grains of the W-xCu composites and enhances their homogeneity. After applying 15 revolutions of HPT on W-30Cu composites, the crystallite… More >

Abstract The two distinct types of composite materials (5% to 10%) were developed using recycled polyvinyl alcohol fiber (RPA), silicon nitride fiber (SN), and reduced carbon nanoparticles (RCN). Enhanced microstructural properties and mechanical strength were attained through the application of the 3-glycidoxypropyltrimethoxysilane coupling method. The combination of the resin-like properties of RPA-SN fiber resulted in the formation of robust outer strength and a high bonding structure. RPA-RCN composite materials with a weight percentage of 10% exhibited a tensile strength of 42 MPa. In contrast, RPA-SN-RCN composite materials containing 5% to 10% demonstrated enhanced tensile, bending, and… More >

Abstract Oil palm fiber is a natural fiber derived from agricultural biomass and has gained significant attention as an alternative reinforcement material in composite materials due to its abundance, renewability, and environmental benefits. This review explores the various enhancement techniques applied to oil palm fiber to improve its properties for composite material development. Key areas of focus include chemical treatments, physical modifications, and hybridization with other fibers to improve fiber-matrix bonding, mechanical strength, and thermal stability. Integration of nanomaterials and bio-based resins to enhance the performance and sustainability of oil palm fiber composites is also discussed. More > Graphic Abstract

Abstract Inverse design of advanced materials represents a pivotal challenge in materials science. Leveraging the latent space of Variational Autoencoders (VAEs) for material optimization has emerged as a significant advancement in the field of material inverse design. However, VAEs are inherently prone to generating blurred images, posing challenges for precise inverse design and microstructure manufacturing. While increasing the dimensionality of the VAE latent space can mitigate reconstruction blurriness to some extent, it simultaneously imposes a substantial burden on target optimization due to an excessively high search space. To address these limitations, this study adopts a Variational… More >

Abstract Polypropylene (PP) has low inherent susceptibility to common industrial lasers, which poses a significant challenge for laser-based marking. To improve the laser sensitivity of PP, molybdenum disulfide grafted with polystyrene (MoS₂-g-PS) was synthesized via in-situ free radical polymerization and used as a laser-sensitive filler for PP composites prepared by melt blending. The composites were then marked with a 1064 nm semiconductor laser, producing clear and legible patterns. The marked surfaces were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), colorimetry, Raman spectroscopy, and thermogravimetric analysis (TGA). The results demonstrate that the PP/MoS₂-g-PS composites exhibit significantly More >

Abstract MoS₂ has excellent properties but low conductivity, limiting its use in supercapacitors. Carbon’s high conductivity and stability enhance MoS₂’s electrochemical performance and cycling stability. This study prepared MoS₂/C composites via a one-step hydrothermal method, exploring the effects of solvents and carbon content. Deionized water as a solvent resulted in composites with large specific surface areas and good electrochemical properties. Increasing carbon content improved electrochemical performance, peaking at a glucose content of 0.28 mmol, achieving a specific capacitance of 202.6 F/g. However, excessive carbon content led to decreased performance. More >

Abstract The increase in energy crisis and environmental concerns are now considering as major hurdle in way to sustainability and clean energy solution. Metal sulfides have been investigated for the fabrication of energy conversion ad storage devices to overcome the effect of energy demand. In this concern, a microemulsion mediated hydrothermal method was employed for the successful synthesis of pure Co₄S₃ and Ce₂S₃-Co₄S₃ binary nanocomposite materials. This study was investigated for Supercapacitor application using cyclic voltammetry and electrochemical impedance spectroscopy. The scanning electron microscope analysis of composite material showed compact smooth morphology with strong interparticle interactions. The More >

Abstract Throughout the composite structure’s lifespan, it is subject to a range of environmental factors, including loads, vibrations, and conditions involving heat and humidity. These factors have the potential to compromise the integrity of the structure. The estimation of the fatigue life of composite materials is imperative for ensuring the structural integrity of these materials. In this study, a methodology is proposed for predicting the fatigue life of composites that integrates ultrasonic guided waves and machine learning modeling. The method first screens the ultrasonic guided wave signal features that are significantly affected by fatigue damage. Subsequently,… More >

Abstract The multiscale computational method with asymptotic analysis and reduced-order homogenization (ROH) gives a practical numerical solution for engineering problems, especially composite materials. Under the ROH framework, a partition-based unitcell structure at the mesoscale is utilized to give a mechanical state at the macro-scale quadrature point with pre-evaluated influence functions. In the past, the “1-phase, 1-partition” rule was usually adopted in numerical analysis, where one constituent phase at the mesoscale formed one partition. The numerical cost then is significantly reduced by introducing an assumption that the mechanical responses are the same all the time at the… More >

Abstract The effect of using 2% and 10% sodium hydroxide solution as surface treatment of rape straw on its water vapor adsorption properties is analyzed in the relative humidity (RH) range of 0% to 98%. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and Fourier-transform infrared spectroscopy (FTIR) are used to investigate the morphological, chemical and structural changes of the treated straw surface.
