Abstract

Ultrasound has been developed as a technique to determine the object and distance detected. It is quite challenging to identify and localise the defects, especially in mechanical parts. Nanomaterials namely multi-walled carbon nanotube (MWCNT), nanoclay and graphene mix with epoxy to be nanocomposites for example which have not been explored using ultrasound method to determine better coupling performance with transducer. Ultrasonic equipment was set up to run the experiment with four main components, namely transducer, personal computer, oscilloscope and indicator whereas to determine the reflection coefficient. Based on the result, nanocomposite of graphene filler gave a lower value of reflection coefficient, which is 0.08299 compared to MWCNT and nanoclay filler of nanocomposites. It is shown that graphene filler of nanocomposite has better coupling performance. The differentiation of the values may be affected by roughness of the nanocomposites.
