| 概要 |
This research focuses on investigating the thermal properties of hybrid composites comprising glass fabric reinforcement integrated with a combination of micro and nano sized fillers. Glass fabric-rei...nforced epoxy composites incorporating varying proportions of micro and nano sized fillers (Al₂O₃, SiO₂, SiC, graphite, MoS₂, and cenosphere) were developed using the hand lay-up technique in conjunction with a bagging process. The developed hybrid composites underwent Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and Thermal Conductivity (TC) testing to assess their thermal properties. Furthermore, an investigation was conducted to correlate the experimental data with the results obtained from mathematical modelling regarding the effective TC of the hybrid composites. From the study, it was evident that the composite containing 5 wt.% of SiC exhibited a glass transition temperature of 146.16°C and a TC of 0.52 W/mK. These hybrid composites demonstrate potential for use in electrical insulation, structural elements in automotive and electronics enclosures, and applications requiring enhanced thermal management in the 100-200°C range. The composite containing cenosphere and MoS₂ exhibited a higher thermal conductivity of 0.68 W/mK and 24% increase in thermal conductivity compared to the base composite.続きを見る
