摘要

In recent years, there has been a notable increase in the usage of natural fibers as reinforcements in polymer composites. However, exposure to high temperatures frequently causes problems for these fibers. Ceramic particles, such as silicon carbide (SiC), are added to them to increase their longevity and thermal stability. The impact of SiC particles on the dynamic mechanical and thermal characteristics of woven bamboo fiber hybrid composites is investigated in this work. In an epoxy matrix, different weight fractions of SiC particles (0, 3, 6, 9, and 12%) were added, and the hand layup process was used to create hybrid composites with three layers of bamboo fiber/SiC. Analysis of the hybridization’s synergistic effects was done using both dynamic and thermal mechanics. The findings showed that with a 6% SiC inclusion, the impact strength (59.4%), tensile strength (30.7%), and hardness (5.9%) were all markedly enhanced by the SiC particles. In addition, the 6% SiC reinforcement generated the maximum thermal stability with increased energy absorption and recovery, according to thermomechanical analysis (TMA) and dynamic mechanical analysis (DMA). The useful contribution of SiC particles to improving the structural and thermal performance of bamboo fiber epoxy composites, which qualifies them for demanding applications, was further validated by fracture analysis.
