Area density of polyimide nanofibers and its influence on the properties of epoxy based nanodielectrics

Popis výsledku v původním jazyce

Recent demands for thin and more resistant materials, that can be used in rotating machines, is causing the evolution of the new generations of materials. Conventional electroinsulating materials include a variety of composite materials, such as the combination of resin, mica and glass fiber cloths. Unfortunately, for effective usage of most composite materials, the thick layer must be used. This affects the space charge accumulation and also thermal conductivity. One of the means to partially eliminate this problem is to reduce the thickness of the entire insulating system. On the other hand, reducing the thickness comes with the reduction of electrical durability. In recent years, the nanocomponents are gaining popularity in various applications. This article presents the experiment of using a combination of commonly used epoxy resin and novel types of non-woven polymer nanofiber materials and modified silicon dioxide nanoparticles. In this experiment, the emphasis was given to the influence concerning the area density of the nanofibers on the electrical parameters of the composite specimen. Based on the results, the influence of the area density has been found. Also, the lower values of the area density have a slightly higher positive effect on the electrical parameters.
