Laser synthesized nanopowders for polymer-based composites

The paper presents the different laser-synthesized carbon and silicon carbide nanostructures used as fillers for composites with epoxy or phenol resin matrix reinforced with glass or carbon fiber. The effect of nanoadditives on the composites’ mechanic and tribologic characteristics is presented. The addition of 2% nanocarbon or 5% SiC has led to the improvement of tensile strength and tensile modulus with 10–15% and 15–20%, respectively. The dry friction coefficient for nanocarbon-containing composites was decreased up to 25% for composites containing nanocarbon, whereas for carbon–carbon composites filled with silicon carbide, this parameter has increased with more than 50%.
