Enhanced switching electric field and breakdown strength of epoxy composites with core‐shell silicon carbide nanoparticles
نویسندگان
چکیده
Silicon carbide (SiC) is widely used to improve the non-linear conductivity of resistive field grading composite. In this paper, SiC nanoparticles are modified into core-shell with silica (SiO2) coating on surface and characterised by transmission electron microscopy X-ray diffraction, respectively. The 7 wt% [email protected]2/epoxy nanocomposite then prepared, pure epoxy SiC/epoxy prepared as a contrast. relative permittivity, thermally stimulated current, breakdown strength studied, presence SiO2 shell around has great effect permittivity trap distribution. nanocomposites show characteristics, compared epoxy. higher switching electric than nanocomposite, which helpful for application composite in higher-voltage equipment or components.

Thermal Sensitive Shape Memory Behavior of Epoxy Composites Reinforced with Silicon Carbide Whiskers
A novel shape memory polymer composite was fabricated by introducing various amounts of silicon carbide whiskers (SiCws) into a shape memory epoxy. The relationship between the thermomechanical properties of the system and structural changes were investigated via dynamic mechanical analysis, scanning electron microscopy, and bending tests. The results show that the bend strength of composites c...

Development of AlN/Epoxy Composites with Enhanced Thermal Conductivity
AlN/epoxy composites with high thermal conductivity were successfully prepared by infiltrating epoxy into AlN porous ceramics which were fabricated by gelcasting of foaming method. The microstructure, mechanical, and thermal properties of the resulting composites were investigated. The compressive strengths of the AlN/epoxy composites were enhanced compared with the pure epoxy. The AlN/epoxy co...
