SILVA, F., SACHSE, S., ZHU, H., PIELICHOWSKI, K., LESZCZYNSKA, A. and NJUGUNA, J., 2014. The effect of matrix and reinforcement material selection on the tensile properties of hybrid composites. Journal of Sustainable Mobility, 1 (1), pp. 37-52.
In order to develop advanced materials as lightweight structures three-phased composites were prepared using nano-fillers, nano-silica (nano-SiO2) and nano-clay and micro glass-spheres to reinforce two kinds of glass-fibre reinforced thermoplastic matrices, polypropylene (PP) and polyamide (PA6). These novel composites were examined for: 1) morphological property using Transmission Electron Microscopy (TEM) and X-ray diffraction; 2) the nature of surface fracture using Scanning Electron Microscopy (SEM); and 3) the mechanical property using Instron 5500R universal testing machine. The results showed that for glass-fibre-PA6 composites, the addition of MMT and glass-spheres enhanced the stiffness, whereas the addition of nano-SiO2 increased the maximum elongation. In contrast the addition of the secondary filler had little effect on the mechanical properties of PP composites.
