| Description
| - Composite materials, two- and three-component in particular, have been used in the field of power engineering for a few decades. Mechanical properties are ranked highest among monitored two-component composite materials. Three-component composite materials are further great at their electrical properties. These materials are composed of carrier component, binder and in the case of three-component material also of filler. A glass cloth or PET foil is ranked among the most often used carrier component. We most often see modified epoxy resins as a binder. Electric barrier is almost entirely provided by mica fillers. Modification of basic resin by nanofillers brings another possibility how to modify and improve parameters of these materials, which are widely used in the field of power engineering, especially for insulating systems of electric machines. Epoxy resin filled by POSS nanoparticles is examined in our workplace in co-operation with the Academy of Sciences. POSS nanoparticles are more complicated elements forming closed structures. This basic scaffold is formed by silicon and oxygen. Number of substances, the most often hydrocarbons, can be linked by this basic scaffold. Epoxy resin examined by us is based on bisfenol-A and contains two kinds of POSS nanoparticles with different level of filling. Two types of hardener were used to their setting. DC and AC measurement and thermal analysis were done. Electrical measurement included observation of dielectric absorption and resorption and out of this findings, rezistivity was calculated. Furthermore, power loss factor tg δ depending on frequency and temperature as well as permitivity was measured. Simultaneous Thermal Analysis ? Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC) ? was realized. Finding optimal filling and testing effects of new fillers on electric and mechanical properties are the next steps planned for this area in the near future.
