Mechanical performance of 3D-printed PBAT composites reinforced with sawdust B.H. Maruthi Prashanth Materials Research Proceedings, 2025 This study examines the mechanical properties of polybutylene adipate terephthalate (PBAT) composites reinforced with sawdust (SD) at varying concentrations (2%, 4%, and 6%), fabricated using 3D printing. The influence of SD content on tensile, flexural, and impact properties was analyzed. The results indicate that incorporating 4% SD yields the best mechanical performance, with a tensile strength of 23 MPa, tensile modulus of 512 MPa, flexural strength of 32 MPa, flexural modulus of 1672 MPa, and impact strength of 98 J/m. However, increasing SD to 6% leads to increased brittleness, reducing tensile strength (21 MPa), tensile modulus (494 MPa), flexural strength (30 MPa), flexural modulus (1459 MPa), and impact strength (89 J/m). These findings demonstrate that SD reinforcement enhances PBAT composites, providing a balance of strength and flexibility, making them suitable for lightweight applications.
An inquisition on alkaline treated Banana/Sisal/Pineapple fiber epoxy composites for light to moderate load applications Pramod V Badyankal, T S Manjunatha, P S Shivakumar Gouda, Maruthi Prashanth B H, C S Srinivasa Engineering Research Express, 2024 To address the sustainable development goals, an attempt was made to investigate the alkaline treated and untreated Banana, Sisal, and Pineapple fiber epoxy hybrid composite for their mechanical and thermal properties. Tensile, Flexural, Impact, modulus, and Heat Deflection temperature (HDT) were evaluated and analyzed for low-load structural applications. The performance of Alkaline Treated Fiber composites was better than the untreated fiber composites. The treated Banana, Sisal, and Pineapple hybrid fiber epoxy composite has a high HDT value of about 78 °C, a maximum tensile strength of 104 MPa, a tensile modulus of 25 MPa, a flexural strength of 78 MPa, a flexural modulus of 5286 MPa,and an impact strength of 286 J m−1 when compared to other composites. Interfacial failure analysis was also carried out with the help of a Scanning Electron Microscope (SEM) to study the microstructural behavior of the tested specimens. It was observed that the alkaline treatment increases fiber-matrix interaction.
