Summary: Glass-fibre-reinforced plastic (GFRP) is popular for various applications due to its high strength-to-weight ratio, stiffness, fatigue resistance, low coefficient of thermal expansion, and tailorable properties. Milling GFRP composites is challenging because of their heterogeneous nature and two-phase structure which result in high cutting forces and delamination. A statistical experiment using the Taguchi design of experiments was conducted to investigate the effect of machining settings on GFRP composite performance metrics.

Summary: Glass fiber-reinforced polymer (GFRP) composite materials are widely used in manufacturing industries due to their low density and high strength properties. However, machining of GFRP composites is challenging due to their anisotropic and heterogeneous structure. This study examined the effects of cutting parameters on cutting force and surface roughness in the turning process of GFRP composites with different orientation angles. An artificial neural network model was established to predict the cutting force and surface roughness based on the machining parameters. The results showed that the minimum cutting force and surface roughness were achieved at low fiber orientation angle, low feed rate, and depth of cut at high cutting speeds.

Summary: With the aim of developing light-weight materials for automotive and aerospace applications, aluminum-based hybrid nano-composites (AHNCs) were manufactured using the compocasting approach in this study. Chopped carbon fibers (CFs) and different weight fractions of nanoclay (1-5%) were reinforced in the matrix of AA6026 to form AHNCs. The AHNCs specimens underwent microstructural analysis, mechanical characterization, fatigue, and corrosion strength tests according to ASTM guidelines. Electroless plating method was used to coat CFs with copper for improved wettability with the matrix. SEM images of the manufactured composites showed thin inter-dendritic aluminum grains with eutectic precipitate particles at intergranular junctions, as well as nanoclay particles precipitated in the matrix. Tensile strength (TS) increased with the inclusion of nanoclay up to a maximum of 212.46 MPa for 3% nanoclay reinforcement, beyond which it decreased due to non-homogeneous distribution, agglomeration, and debonding of nanoparticles. Similarly, micro-hardness increased with the addition of 3% nanoclay, after which it decreased. Higher energy absorption and significant improvement in flexural strength were achieved with 3% nanoclay reinforcement. The fatigue strength of the hybrid composite tended to increase with the addition of both CFs and nanoclay until 3% addition, as the flexible CFs and high surface area nanoclays strengthened the grain boundaries. Furthermore, the addition of nanoclay reduced the corrosion rate by filling the crevices and voids in the matrix.

Summary: The effect of critical plasma spraying parameter (CPSP) and spraying distance on scratch and wear characteristics of alumina-zirconia coatings deposited on Ti-6Al-4 V was studied. Wear resistance, scratch resistance, microstructure, and hardness of the coatings were evaluated through various analyses. The increase in CPSP and spraying distance improved the wear and scratch resistance as well as micro hardness of the coatings. Coatings deposited at a distance of 100 mm exhibited the highest scratch and wear resistance. The wear mechanisms observed included splat delamination, microchipping, and microcracking.
