Mechanical, thermal, and tribological improvement of jute fiber-epoxy composites using fish scale biochar Sudarsan Deenadayalan, Karthick Rasu, Thanga Kasi Rajan Selvaraj, Karthikeyan Samayan Materialpruefung Materials Testing, 2026 This study investigates the effectiveness of fish scale biochar as a sustainable micro-filler for enhancing the mechanical, thermal, and tribological performance of jute fiber–reinforced epoxy composites. Six composite formulations were developed by varying the biochar content from 0 to 10 wt.% while maintaining a constant jute fiber loading of 45 wt.%. The incorporation of biochar significantly improved the composite properties, with the 4 wt.% formulation (JF-FSB4) exhibiting the highest tensile strength (61.48 MPa), flexural strength (100.63 MPa), interlaminar shear strength (20.47 MPa), tensile modulus (3.69 GPa), flexural modulus (4.65 GPa), impact strength (13.72 J), and hardness (76.58). Wear resistance increased progressively up to 6 wt.% biochar due to improved surface integrity and enhanced load-bearing capability, whereas higher filler levels resulted in performance reduction attributed to particle agglomeration. Water absorption decreased to a minimum of 2.98 % for the JF-FSB6 composite, indicating enhanced moisture resistance. Thermal conductivity increased steadily from 0.24 to 0.39 W/m·K with increasing filler content, driven by the formation of conductive carbonaceous pathways. Overall, the results demonstrate that fish scale biochar serves as an effective eco-friendly filler capable of improving mechanical stability, thermal performance, and wear resistance, making these composites suitable for lightweight engineering applications.
Effect of benzoylation surface treatment on the physical, mechanical and thermal properties of aloe vera fiber reinforced polyester composites Kamatchi Thirupathi, Karthick Rasu, Meby Selvaraj Rajachandrasekaran, Sudarsan Deenadayalan Materialpruefung Materials Testing, 2026 The growing demand for sustainable materials has driven interest in natural fiber-reinforced composites. Aloe vera fiber is biodegradable and abundant but suffers from poor adhesion with polymer matrices, limiting its structural use. This study aimed to enhance the interfacial bonding of aloe vera fiber-reinforced polyester composites through chemical surface modifications. Fibers were subjected to alkali treatment using sodium hydroxide and subsequently benzoylated with benzoyl chloride at concentrations of 5, 10, 15, and 20 %. The composites were evaluated for hardness, tensile, flexural, impact, and shear strengths, along with water absorption and thermal conductivity. Results showed that alkali treatment improved adhesion and reduced moisture uptake, while benzoylation further enhanced mechanical performance. The AVF-B20 composite exhibited superior properties, including a hardness of 66.98, impact strength of 6.62 J, tensile strength of 67.30 MPa, tensile modulus of 4.9 GPa, flexural strength of 88.68 MPa, flexural modulus of 4.05 GPa, shear strength of 13.96 MPa, and the lowest water absorption of 3.62 percent. A slight rise in thermal conductivity was observed with increasing benzoylation levels. Overall, combined alkali and benzoylation treatments effectively improved the strength, durability, and dimensional stability of Aloe Vera fiber composites, making them suitable for sustainable engineering applications.
Experimental Study on Drilling Performance of Bio-Waste-Based Corn Husk Fiber Reinforced Epoxy Composites for Green Applications Karthick Rasu, Ashwin Prabhu Gnanasekaran, Sudarsan Deenadayalan, Kuntanahal Rajashekhara, Kamalakannan Ranganathan, et al. Journal of Manufacturing and Materials Processing, 2026 This study focuses on the machinability optimization of bio-waste corn husk fiber–reinforced epoxy composites during drilling, with the objective of minimizing delamination and improving hole quality required for mechanical fastening applications. While natural fiber composites have been widely investigated, systematic statistical optimization of drilling parameters for corn husk fiber composites remains limited. The novelty of this work lies in identifying the dominant drilling parameter and establishing a clear damage-control strategy using a Taguchi L16 design coupled with ANOVA. Drilling experiments were conducted by varying spindle speed (1000, 1500, 2000, and 2500 rpm), drill diameter (6, 8, 10, and 12 mm), feed rate (00.05, 0.10, 0.15, and 0.20 mm/rev), and point angle (90°, 100°, 110°, and 120°). The results show that the drill diameter is the governing factor affecting delamination, contributing 73.52% of the total variation, followed by spindle speed (22.68%), whereas feed rate (3.14%) and point angle (0.38%) have minimal influence. The optimal condition (2500 rpm, 6 mm drill diameter, and 0.05 mm/rev feed rate) produced the lowest delamination and improved surface integrity. Microscopic observations confirmed reduced fiber pull-out and matrix cracking under these conditions. The main advantage of the proposed approach is the clear identification of parameter priority, enabling the industry to control drilling damage by primarily selecting appropriate drill diameter and spindle speed. The findings provide practical machining guidelines for the use of corn husk fiber composites in lightweight panels, automotive interior parts, and secondary structural components where reliable bolted joints are required.
Investigate the mechanical properties of Aluminium Metal Matrix Composite Ramesh Vellaichamy, D. Sudarsan, R. Theerkka Tharisanan, Mothilal Allahpitchai, B. Radha Krishnan Journal of Physics Conference Series, 2024 The objective of this study is to produce metal matrix composites with aluminium as the matrix material and beryl as the reinforcing particles. Given the comparable density of beryl particles to Aluminum-based alloys, it is anticipated that enhancements in strength and ductility properties will lead to increased mechanical and tribological characteristics, including hardness and wear resistance. Extensive research has been conducted on aluminum-based metal matrix composites (MMCs) in the recent past, specifically focusing on the utilisation of ceramic reinforcements such as silicon carbide (SiC), titanium nitride (TiN), Titanium Diboride (TiB2), zirconia (ZrO2), and alumina (Al2O3). Typically, the ceramic particles employed for reinforcement exhibit notable hardness and high density, resulting in enhanced hardness and improved Tribological wear characteristics. Aluminium-based metal matrix composites (AMMC) were produced by including varying concentrations of beryl (3%, 8%, and 13%) through two distinct fabrication methods: the liquid metallurgy vortex route and the powder metallurgy approach. The beryl mineral phase was initially subjected to crushing and mechanical sieving processes to get particle sizes with an average of 50 ± 10 and 100 ± 10 μm. The mechanical qualities, including hardness and tensile strength, were examined using the Brinell hardness machine and the Universal testing equipment.
