Investigation on the mechanical and moisture uptake properties of epoxy-Terminalia arjuna fiber natural composites containing nano-silica
Natural composites are gaining attention among researchers due to its characteristics like low density, eco-friendliness, and cost-effectiveness. However, their performance falls short when compared to traditional materials, necessitating research focused on enhancing the strength of natural composites. The limited attention given by researchers to Terminalia arjuna fiber, a natural fiber, prompted an exploration to unveil novel scientific insights into Terminalia arjuna fiber-based composites. This study involved the creation of a natural composite through the hand layup process, combining Terminalia arjuna fiber and epoxy resin. Additionally, nanofiller like silica (SiO2) were introduced as reinforcing agents. Various materials were fabricated for different weight percentages of fiber and particles. The assessment covered mechanical and water absorption characteristics. The composite composed of epoxy with 30 wt% Terminalia arjuna and 2 wt% SiO2 showcased excellent mechanical properties, including high tensile strength (74 MPa), flexural strength (98 MPa), impact resistance (6.6 kJ/m2), and hardness (90 shore-d). Furthermore, it demonstrated minimal water absorption (18.4 % after 10 days). This research suggests that the epoxy/Terminalia arjuna/2 wt% SiO2 composite could be a preferred choice for industrial applications due to its outstanding performance.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
