摘要

Impact strength of a PBT/PC blends was tested at different strain rates. It was found that when fracture occurred under plane strain condition the impact fracture toughness of the PBT/PC blends with strong interface obeyed the rule of mixtures. But when fracture took place Under non-plane strain condition, the toughness of the blends was much lower than that predicted by The rule of mixtures and negative blending effect was observed.
