The samples are prepared through melt extrusion followed by injection moulding. The Scanning elec- tron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) results show that SB-rPP composites have a fairly strong interfacial interaction and a change in crystallization for the highest containing SB composite, however, some fibre pull-outs are observed as the SB content is increased. The interaction influences the thermal and mechanical properties of the samples in a complex way. There are strong indications of a stronger interfacial interaction on the highest containing SB composite, which is supposedly accountable for the increased crys- tallinity and melting temperature.

Introduction Interest in composite materials reinforced with natural fibres has recently increased considerably due to some natural benefits of the fibres. These materials present low cost, low density, high specific properties and are * Corresponding author.
