Processing controlled properties of vibration welded thermaplastic-based nanocomposites
In the present work, polypropylene based nanocomposites were compounded using a twin-screw extruder followed by injection molding. The related plaques were joined by linear vibration welding. The mechanical performances were examined by using Charpy impact testing. It was found that the incorporation of rigid particles improved the impact strength of polypropylene. The maximal impact strength was achieved at 1 vol.% TiO2 filled polypropylene. By contrast, the impact strength of the welds decreased with increased nanoparticle contents. The highest weld strength was achieved at low welding pressure without nanoparticles. In comparison to non-welded samples low mechanical performance currently do not allow to transfer the reinforcing effects of nanoscale fillers into welded structures.
