Abstract

Composites obtained from polypropylene (PP) and nettle fibers were manufactured by an extrusion method. The samples for mechanical and structural testing (by Wide Angle X-ray Scattering (WAXS) and Differential Scanning Callorymetry (DSC) methods) were obtained by an injection molding method. The tests showed that PP composites reinforced with nettle fiber show satisfactory properties and confirmed usefulness of nettle fibers as a reinforcement material. It was found that nettle fiber shows strong properties nucleating the growth of crystalline structures in the PP matrix. In addition, the presence of hexagonal forms in PP matrix was found in the samples obtained by injection molding.
