Mechanical behavior of fibers and films based on PP/Quartz composites
Source abstract
Abstract
In this work, films and fibers of polypropylene based composites reinforced with quartz were investigated. The materials were processed in a twin screw extruder with filler contents of 1, 2.5, and 5 wt%. Morphology, thermal properties, and mechanical behavior of these materials were studied. A homogeneous filler dispersion and particle alignment in the extrusion direction was detected for the films. Thermograms displayed a marginal nucleating effect of quartz particles. Uniaxial tensile tests indicated a high ductility level and strain hardening for the composites processed as films (in the extrusion direction). Single fiber tests displayed improved tensile properties compared with the same materials produced as films. Quasistatic fracture tests showed a completely ductile behavior for the films in the extrusion direction. In addition, films fracture toughness was found to increase with filler content. POLYM.
