Effect of Thermal Stress on the Hybrid Fibre/Particle Nanocomposite

Nanocomposites are the next generation of materials for various types of applications. Their advantageous properties are now often used in modern applications as coatings or as gas barriers. In the future, the combination of conventional materials and nanocomponents will be more visible than it is today. This is due to their enhancing effect on the base material. Today's experiments with nanocomponents also include commonly used high voltage materials, such as epoxy resin. In combination with nanocomponents, the positive effect on the electrical, mechanical and also chemical properties is observed. One of the important attributes is a life span of the material, which means the preservation of optimal parameters in time. Importance of investigation of life span is to predict the time in which is safe to use the material without damaging the machine or, in the worst scenario, hurt a person. This article presents an experiment where the electrical parameters of nanocomposite materials under thermal stress are investigated. Pure epoxy resin, epoxy resin with nanoparticles and epoxy resin with hybrid nanoparticle/nanofiber filler were exposed to a temperature of 220 °C for 1000 hours. The positive influence of nanocomponents on the life span is observed.
