Abstract

The effect of blending sequence on the morphology and mechanical properties of short glass fibers (SGF)/rubber/recycled poly(ethylene terephthalate) (r-PET) ternary blends was investigated. It was found that the compounding blending sequence has a strong influence on the tensile strength of the blends, and the blends obtained by mixing maleic anhydride grafted styrene-ethylene/ butylenes-styrene triblock copolymer (MA-g-SEBS), r-PET and SGF, C1-blends, had a tensile strength of about half of the mixed MA-g-SEBS, r-PET and SGF blends, C-2 blends. The average fiber lengths for the C-1 and C-2 blends, by burning off the rubber/r-PET matrix and counting the fiber length distributions, were found to be similar, at 0.31 and 0.36mm, respectively. It was observed that the flexure bending strength for C-1 was significantly higher than that for C-2.
