Ceramic-epoxy composite transducers for non-contacting ultrasonic applications

Research output: Contribution to journalArticlepeer-review

Abstract

This work describes the evaluation of various 1-3 connectivity transducer configurations, comprising a matrix of ceramic rods embedded in epoxy, for operation into air over the frequency range 100 kHz - 2 MHz. A dual strategy, involving simulation design and supported by experimental verification, is used to determine the main factors which influence through air operation of such structures. Specifically, finite element analysis is employed to determine the influence of ceramic rod shape and distribution, in conjunction with the characteristics of the epoxy filler materials, on transducer performance. A one dimensional linear systems model is then utilised for assessment of transducer behaviour when configured as an actual probe assembly and connected to practical electrical and mechanical load environments. Some experimental examples, relevant to non-destructive evaluation are presented, including through transmission scanning of carbon-fibre composite materials and remote detection of laser generated ultrasound.
