Types and Applications of Chemochromic Sensors
Abstract: Smart materials, also known as responsive or intelligent materials such as chemochromic materials changes colour upon exposure to a different environment or when react with different chemicals. Chemo chromic sensors are specially designed for robustness and can be used for leak detection in the vicinity of connections, valves, or Hydrogen line outlets. They can be altered, nevertheless, for a variety of uses. These are the materials whose colors and reflective …

Influence of Corrosion on Flexural Strength of Concrete
Abstract: The large-scale infrastructure uses reinforcement concrete. It has been believed that protection to steel reinforcement by concrete is permanent. The influence of atmospheric corrosion of steel and its performance in concrete has been subject to controversy in the construction industry. Service life of reinforced concrete structure can be significantly reduced when the corrosion of reinforcing steel is initiated; the product of corrosion expands and occupies greater volume than original volume …

Comparative Analysis of Tensile Properties of Virgin and Rice Husk-Reinforced PLA and ABS Filaments
Abstract: This study focuses on evaluating the tensile behavior of polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) filaments reinforced with rice husk ash (RHA) particles, in comparison with their respective virgin counterparts. The incorporation of RHA, an abundant agricultural waste by-product, was considered with the objective of developing eco-friendly composites suitable for additive manufacturing applications. Tensile testing was carried out to assess the influence of the reinforcement on the mechanical …

Assessment of Matrix Cracking and Fiber Breakage in Hybrid Composite Materials.
Abstract: Hybrid composite materials, combining two or more distinct fiber or matrix constituents, have emerged as advanced structural solutions for aerospace, automotive, marine, and civil engineering applications. However, their complex microstructure makes them susceptible to multiple interacting damage mechanisms, particularly matrix cracking and fiber breakage. This study provides a comprehensive assessment of these damage modes, emphasizing their initiation, evolution, and combined effects on the mechanical integrity of hybrid composites. Matrix cracking …

Effect of Thermal Conditions on Microstructure and Mechanical Properties of AA5083 Processed by Equal Channel Angular Pressing
Abstract: A commercial AA5083 with an initial grain size of 210 μm was given an ultrafine-grained structure using the equal channel angular pressing (ECAP) technique under die design as patented. The identical sample underwent two successful passes through the die at 473 K, with each passage causing the sample to rotate 90° along its own longitudinal axis. After just one pressing, the microstructure was comparatively homogeneous. It was made up of …

Tensile and Microstructural Behaviour of Friction Stir Welded AL7050 Hybrid Composites Reinforced with Multani Mitti and Cow Dung Ash
Abstract: The study examines Al7050 aluminum alloy composites made by stir casting and bonded by friction stir welding (FSW), supplemented with environmentally friendly Multani Mitti (MM) and cow dung ash (CDA). The study assesses the effects of different hybrid reinforcement contents (0–8 vol%) on the microstructural properties, hardness, and tensile behavior of the base alloy and its FSW joints. Tensile testing reveals an initial decline at 2% reinforcement but a notable …

Wear and Tribological Characteristics of Novel Metal Matrix Composites
Abstract: The development of advanced metal matrix composites (MMCs) with enhanced tribological performance has become increasingly important due to the premature failure of critical engineering components operating under severe wear conditions in automotive, aerospace, marine, defense, and power generation systems. Conventional composites such as Copper–Alumina and Aluminium–Silicon Carbide have demonstrated improved mechanical and wear characteristics; however, their widespread application is often limited by issues including particle agglomeration, non-uniform reinforcement distribution, porosity …

Ultrasonic Dispersion of Halloysite Nanotubes for Enhanced Mechanical, Thermal, and Morphological Performance of Epoxy Composites
Abstract: Halloysite nanotube (HNT)-reinforced epoxy nanocomposites were prepared by mixing HNT with bisphenol-A epoxy (LY 556) using ultrasonication, followed by compression molding. HNT contents of 0–5 wt.% were used. The composites were evaluated for tensile strength, flexural strength, Shore D hardness, Izod impact strength, and thermal stability using thermogravimetric analysis (TGA). The fractured tensile surfaces were also examined to understand the failure mechanism and interaction between HNT and the epoxy matrix. …
