Experimental investigation on dielectric properties of composites using Taguchi technique

Abstract

Flexible composites find applications as dielectric elastomers. These composites are used as actuators and sensors. Solid silicone rubber-conductive filler composites are promising candidates for above applications. They are fabricated using compression moulding and evaluated for their dielectric properties, using Taguchi design of experiments. The influence of factors such as filler and curing agent loading, mixing time, curing temperature on the dielectric properties are presented. Permittivity increased to 14.1 and dielectric loss increased to 1.27 for the conductive filler loading of up to 12 parts per hundred rubber, while still being in insulator regime. © 2019 Elsevier Ltd.
