| 概要 |
Composites have limitless engineering applications where strength-to-weight ratio, low cost, and ease of manufacture are needed. This study presents to synthesize and evaluate the mechanical and therm...al properties of sisal, bamboo, and hybrid fiber-reinforced composites. Combined chemical and enzyme-assisted extraction methods were employed to extract bamboo fibers, while sisal fibers were extracted using a fiber-extracting machine. Due to the variations in lignin, hemicelluloses, pectin, and wax content and strength among natural fibers, both fibers were subjected to different concentrations of treatments over varying periods. Composites were fabricated using the hand lay-up method considering 0, 45, and 90-degree fiber ply orientation angles. Unsaturated polyester mixed with Methyl ethyl ketone peroxide is used as a matrix. From the experimental analysis, it has been identified that bamboo fiber-reinforced composites exhibited 140.17 MPa tensile strength with a maximum tensile modulus of 2,595.74 Pa. The variation in tensile strength was significantly affected by the fiber orientation, whereas the compressive strength was influenced by both the fiber type and orientation. As a sample is continually weighted while heating, the bamboo fiber-reinforced composites had a lower mass change and thus, are thermally stable compared to sisal and hybrid composites. ANOVA results for tensile and compressive strength showed that fiber orientation contributed 83.79% for tensile strength and 47.38 % for compressive strength, whereas fiber type contribution was 5.23% and 46.97 %, respectively. Intending to utilize natural fiber-reinforced composites in applications requiring both structural and thermal stability, the study contributes to the advancement of environmentally friendly materials for the applications prioritizing environmental sustainability and technological innovation.続きを見る
