We demonstrated a method for selective etching of polyphenol–matrix composites which leads to improvement of the insulation properties. The selective polymer removal improved tracking properties of the 70% glass filler reinforced composites up to 56%, whereas the performance level decreased with the decrease in filler content. This technology provides an important enhancement of polymer–matrix composites' tracking properties and resistance of composites to electrical short-circuit fire.

The article reports on reciprocal influence between the sample surface and atmospheric plasma jet. We have shown that sample material and its distance from the tip of the electrode have a pronounced influence on atmospheric pressure plasma jet electromagnetic and optical characteristics, such as jet length, shape, color, voltage, current, power, electromagnetic field and concentrations of plasma species. Research was performed in collaboration with Institute of Physics, Zagreb.
