Mechanical Properties, Viscoelastic and Water Absorption Properties of Biocarbon-Reinforced Composites

By Nagasrisaihari Sunkara, S. John Leon, S. Senthil Kumar, Geetha Chandrasekran, S. Baskar, R. Ashok Kumar

Abstract: Biocarbon-reinforced polymer composites have emerged as a sustainable alternative to conventional composites, combining environmental benefits with promising material properties. This study explores the effect of varying biocarbon content (0%, 10%, 20%, and 30% by weight) on the mechanical, viscoelastic, and water absorption properties of a polypropylene (PP) matrix. Tensile strength tests reveal that incorporating 10% biocarbon yields the highest strength at 35 MPa, attributed to enhanced interfacial bonding. However, at …

ANN Approach to Forecasting the Strength of Nano Silica Incorporated Geopolymer Composite

By Sagar Paruthi, Ibadur Rahman, Asif Husain

Abstract: Coal and steel industry by-products, such as fly ash (FA) and blast furnace slag (GGBS), have gained significant attention as precursors for geopolymer concrete (GPC) due to their high aluminosilicate content, offering a sustainable alternative to conventional cement. Nano silica (NS), recognized for its exceptional pozzolanic activity and ability to refine microstructure, has shown potential to enhance the mechanical and durability properties of GPC. This study investigates the influence of …

Marine Algal Microfiber and Agro-Waste Reinforced Crosslinked Polymer Composites for Sustainable Coastal Materials

By Sravanthi Gudikandula, R. Anandhakrishnan, Jai Shanker Pillai H.P., M.P. Indumathi, S. Parameswari, Sivakumar S., Arun K.K., J Sharmila, Zakir Hussain

Abstract: Crosslinked bio-polymer composites reinforced with marine algal microfibers and agro-waste fillers were fabricated and systematically characterized for sustainable coastal applications. Mechanical testing revealed that tensile strength increased from 18.5 MPa for neat polymer to 25.1 MPa at 20 wt.% reinforcement (~35% improvement), while the flexural modulus improved from 0.72 GPa to 1.02 GPa (~42% increase). Impact strength, however, decreased from 3.8 kJ/m² for neat polymer to 2.9 kJ/m² at 30 …
