Abstract
The effects of filler volume fraction (φf) and filler diameter (d) on the elastic storage moduli of low density polyethylene/glass bead (LDPE/GB) composites have been investigated by using a dynamic mechanical analyzer in the present paper. The fillers used were GBs of different diameters: 4, 11, 35 , 49, 93, 114 and 180 μm, which were blended with LDPE by means of a twin screw extruder to produce the composites. It was found that the elastic flexural storage modulus (Ec') and the elastic shear storage modulus (Gc') of the composites increased non-linearly with increasing φf but the influence of d on Ec' and Gc' was not significant. On the basis of the previous work, a semi-empirical equation describing the correlation between the relative elastic flexural storage modulus (ER') and φf was proposed. The predicted values of ER' are in good agreement with the experimental ones.
