    The mechanical and adhesive properties of electrically and thermally conductive polymeric composites based on high density polyethylene filled with nickel powder حسب Krupa, Igor

    منشور في 2013
    "…The stress at break of the composites behaved nonlinearly; the low filler content suppressed necking, resulting in a decrease in stress at break, whereas higher filler content (higher than 10vol.%) led to reinforcement of the composites and therefore increased the stress at break.The presence of nickel particles throughout the HDPE matrix increased the hydrophilicity of the composites. …"
