Notes:
Although much research work has been conducted on the production and characterisationof polypropylene/organoclay nanocomposites, the effects of nanoscale fillers with respect to actualmorphology through numerical modelling have been rarely addressed. This paper describes aunique development from fabrication and experimental characterisation to the numerical modellingof polypropylene/organoclay nanocomposites based on the real mapping of nano/microstructures.Twin screw extrusion is used with a two-step masterbatch compounding method to prepare suchnanocomposites with organoclays (ranging between 1wt% and 10wt%) and maleated polypropylene(1:1 weight ratio). The material characterisation using X-ray diffraction (XRD), scanning electronmicroscopy (SEM) and dynamic mechanical analysis (DMTA) are conducted and mechanicalproperties are determined by tensile, flexural and impact tests. Finally, computational models areestablished by using an innovative object-oriented finite element analysis code (OOF) to predict theoverall mechanical properties of nanocomposites
