Research on Tensile Strength in the Ultrasonic Welding Joint of T-type Wood-Plastic Composites Components

摘要

Ultrasonic welding technology is applied to the connection of T-type wood-plastic composites components to study its performance. The wood-plastic composite materials are made up of 60% wood-flour (WF), 36% polypropylene (PP) and 4% maleic anhydride grafted PP (MAPP). Tensile strength of the welded joint, which oscillation time is 4 seconds, is analyzed based on experimental data. Welded joint is observed by scanning electron microscope and its connection status is analyzed. Experiment results show that ultrasonic welding technology can be applied to T-type wood-plastic composites component, which has enough tensile strength.
