Abstract

Tests were performed to evaluate the effect of thermal shock behavior on the mechanical properties of PC(poly-carbonate) and PET(polyethylene-terephthalate) with MBS(methylmethacrylate-butadiene-styrene) alloy. Five different material weight fraction for PC/PET were employed : 0/100, 25/75, 50/50, 75/25, and 100/0. Three different weight fraction of MBS were added to each PC/PET : 0, 3, and 9. Therefore fifteen different types of PC/PET/MBS were prepared using single screw extrude. and injection molding machine. One thermal shock cycle consisted of each one hour stay at -$40^{\circ}C$ chamber and $＋80^{\circ}C$ chamber without delay. Specimens were thermal shocked up to 20 and 40 cycles. Specific mechanical properities considered in this study include tensile, izod impact, and high rate Impact behaviors. In addition, the morphology of the fractured surface after Izod impact testing was investigated by the SEM (scanning electron microscope).
