Effect of Iron and Aluminum Powders on the Properties of Composites with Isotactic Polypropylene

It is studied the behavior of composite materials with isotactic polypropylene (iPP) matrix and iron (Fe) and aluminum (Al) metallic powders. Concentrations of metallic powders were 3, 5 and 8 %. The raw materials are mixed in a turbula in the required quantities and the melt is injected in the form of the samples used in the measurements. The Al and Fe powders had two granulations. A comparative study is made in the case of materials for the mechanical, thermal and electrical characteristics. Differential Scanning Calorimetry (DSC) and Scanning Electron Microscopy (SEM) measurements allowed to explain the changes in the structure.
