Investigation of contact surfaces between polymer matrix and metallic glasses in composite materials based on high-density polyethylene

摘要

In our research we obtained composites based on high-density polyethylene (HDPE) reinforced with Mg_(67.5)Ca_5Zn_(27.5) metallic glass by co-extrusion and compression. The co-extrusion and compression procedures have been provided at temperatures of supercooled liquid temperature region of both materials (between the glass transition temperatures (T_g) and crystallization temperature (T_x)). We investigated the mechanical properties and performed the structure characterization of the obtained polymeric/metallic glass composite samples. A positive effect of triethoxyvinylsilane on the adhesion between polymeric matrix and metallic glass reinforced particles was discovered. It was also found that composite samples (HDPE/Mg_(67.5)Ca_5Zn_(27.5)) had excellent adhesion, good thermal conductivity and high modules of elasticity. The metallic glassy samples demonstrated good dimensional stability after treatment by the 10 mass% of the triethoxyvinylsilane.
