THE INFLUENCE OF SILICA NANOPARTICLES ON MECHANICAL
Two types of silica nanoparticles have different influence on the characteristics of the same PLA matrix. The addition of 0.05 wt. of T120 and N999 silica nanofillers improved mechanical properties due to their good dispersion in PLA matrix. Increasing silica content the tensile strength and elongation at break were decreased.
