Resumen:
Nanocomposites based on Polypropylene and carbon nanotubes were used as the matrix in self-reinforced composites. Morphological, thermal and mechanical characterization was performed. Electrical behavior was investigated to analyze the materials ability to monitor damage from strain-induced electrical changes. Nanocomposites obtained at high extrusion speed presented better filler dispersion and hence, improved tensile and electrical response. Processing conditions mainly affected the composites consolidation quality and thus, their failure mode. While poorer consolidated materials presented delamination, those better consolidated mostly failed by fiber fracture. Composites with an open PP fabric exhibited electrical resistivity values adequate for strain sensing but worse tensile properties.
