| Summary: | 碩士 === 國立交通大學 === 工學院碩士在職專班精密與自動化工程學程 === 94 === This study focuses on the tensile strength affected by shearing operation on PC/ABS blends during an injection-molding process. A mold which can control shearing rate is adopted to perform different shearing rates to melting state of PC/ABS blends on actual holding pressure stage. Then, the tensile strength of the specimens are tested according to a specification of the tensile-strength standard.
This result shows that the tensile-strength values increase after shearing as the weight fractions of PC are under 80% in the PC/ABS blends.
