Abstract
This research examines the mechanical and thermal characteristics of composites made from nettle fiber-reinforced wheat bran filler particulate epoxy framework. It highlights the influence of different filler materials on the performance of these composites. A thorough examination of mechanical properties was carried out, focusing on the flexibility, bending strength, impact resistance, and Shore D hardness. The malleable quality was completely changed by adding a filler ingredient, reaching a peak of 51.36 MPa. The flexural strength reached 47.38 MPa, showing excellent ability to withstand loads. The assessment of affect quality reached a maximum of 13 kJ/m2, indicating high energy absorption and durability. The Shore D hardness, which indicates the surface’s ability to resist indentation, ranged from 52 to 61, indicating differences in the stiffness of the composite material. The addition of bran filler to this composite provides an ideal thermal conductivity value of 0.98 W/mK. The morphological properties of the composites were analysed using Scanning Electron Microscopy (SEM), which provided detailed insights into their internal structure. The SEM images revealed a uniform distribution of nettle filaments and bran fillers inside the epoxy matrix, with well-formed samples exhibiting strong fiber–matrix adhesion and minimal voids.
期刊介绍:
Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
