Nanoarchitectonics of ethylene propylene diene monomer (EPDM) composites reinforced with Cu–Al–Zn-alloy for ultrasonic array transducers’ fabrication

Abstract In response to the continuous demand for industry progress and need low-cost alternative materials that have superior properties than present ones, a new coupling agent was used treat composites, which were as backing in ultrasonic array transducers. transducers, back-echo reverberation piezoelectric elements occurs, so are critical reducing these echoes. The Cu–Al–Zn-alloy treated with before being incorporated into ethylene propylene diene monomer (EPDM) composites. Cu–Al–Zn-alloy/EPDM composites assessed using rheometric, mechanical, morphological properties. division of cu-alloy at EPDM matrix visualized scanning electron microscope (SEM). TGA DSC techniques study thermal characterization As result, Cu-alloy improved thermal, characteristics Ultrasonic measurements ensured composites' effectiveness Furthermore, composites’ similar those most commonly epoxy/tungsten material. Finally, linear ultrasonic-phased transducers fabricated They had low signal-to-noise ratio, this materials.
