Summary: Wear parameter optimization is critical for the successful use of materials in load-bearing applications. This study examines the optimization of various wear parameters using the Taguchi technique for the determination of the specific wear rate of alpha-manganese dioxide (alpha-MnO2)-epoxy nanocomposites. The results show that the specific wear rate can be significantly reduced by adding 0.5% weight percent loading of alpha-MnO2 in epoxy.

Summary: The research found that the roselle fabric composite has superior mechanical properties, while the sisal fabric composite has lower tensile and impact strengths. However, the sisal fabric and roselle fabric composites have similar flexural properties. The sisal fabric composite has the highest loss factor peak, with the peak height increasing with higher sisal fiber content in the roselle/sisal fabric composites.

Summary: This study investigates the impact of different fiber loadings on the dry-sliding wear behavior of natural fiber reinforced polymer composites. The results show that the addition of short areca-catechu fibers significantly improves the wear resistance of the composites. An optimum fiber content is determined for the lowest wear rate. Additionally, a predictive equation is proposed to estimate the specific wear rate of the composites under varied test conditions, which shows good agreement with experimental results.

Summary: The wear properties of GONs-EP nanocomposites were significantly improved by incorporating silanized GONs into the matrix. Among different loading levels, 0.3 wt% silanized GONs showed the best wear behavior. The amino-silane coupling agent was found to be more effective in enhancing the wear resistance of the GONs-EP nanocomposites.

Summary: The study investigates the friction and sliding wear behavior of neat glass-fiber-reinforced epoxy polymer (GFRP) and GFRP filled with 1 wt% graphene nanoplatelet (GFRP/1%GNP) composites under dry, inert gas, and oil-lubricated conditions. The results indicate that the specific wear rate and coefficient of friction vary significantly depending on the lubrication condition, with GFRP/1%GNP composites performing best under oil-lubricated conditions.

The results showed that the chemical treatment improved the morphological properties of the fibers, reduced the hemicellulose and lignin contents, and enhanced the thermal, mechanical, tribological, and morphological characteristics of the composites. The sodium citrate treatment was found to be more effective than the stearic acid treatment in improving the mechanical and tribological properties.

Summary: The purpose of this work is to evaluate the effectiveness of low-cost and environmentally friendly chemical modification on jute fibre-reinforced epoxy composites (JFREC) using sodium hydroxide (AT), sodium carbonate (ST), and sodium hydrogen carbonate (SHT) in terms of morphology, water absorption, mechanical, and tribological characteristics. Results showed significant improvement in mechanical properties such as tensile strength, tensile modulus, and impact strength for AT JFREC (38.08%, 30.56%, 31.66%), ST JFREC (70.03%, 33.06%, 41.30%), and SHT JFREC (24.69%, 8.88%, 22.61%) compared to untreated JFREC. The study also confirmed that the chemical modification improved fibre-matrix adhesion, leading to enhanced water absorption resistance and tribological properties of the modified JFREC. The improved mechanical and tribological properties make the chemically modified JFREC potentially applicable in automotive and packaging industries.
