عنوان انگلیسی Experimental Analysis of Effects of Ultrasonic Welding on Weld Strength of Polypropylene Composite Samples
چکیده انگلیسی مقاله In the present study, method of ultrasonic welding of plastics is used to join the overlap of Polypropylene composites reinforced with glass fiber. The effects of process parameters, including time, pressure, vibration amplitude and amount of glass in composite on strength of welds. To reduce the number of tests and cost, the effect of changing parameters on strength was examined through Box-Behnken test by considering four factors at three levels and parameters were optimized to obtain the highest level of strength. The results of present study showed that maximum failure force is about 2.30 KN, and it is observed when air pressure is 1.5 times more, and amplitude is close to more than 32 micron (more than average), length of welding is 0.4 second and amount of glass used is about 10 percent.
