Abstract
In this study, a modified hybrid rule of mixtures equation (HROM) was presented to predict the tensile moduli of hybrid composites. Experimental data from single fibre reinforced thermoplastics formed the basis of the modification. Combinations of E-glass, hemp and hardwood flour were blended into HDPE in total fibre loadings of 10 to 60 wt% to produce hybrid composites. The density and Young’s modulus of the hybrid composites fell between the extreme values obtained for the single fibre composites. It was shown that by adding E-glass fibres or hemp fibres to hardwood flour, the tensile modulus of the single hardwood reinforced thermoplastics could be increased with a minimal increase in density. The modified rule of hybrid mixtures equation was found to adequately predict the tensile modulus of the hybrid composites. 9 refs.
