[ 1 ] - Experimental Analysis of Effects of Ultrasonic Welding on Weld Strength of Polypropylene Composite Samples

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-Be...
