Abstract

New 1-3 piezocomposite materials have been investigated for potential underwater smart skin applications. PZT-5H was used as the ceramic phase in the composite whereas two types of polyurethane resins of different hardness were used as the matrix of the composite in order to assess the effect of the compliance of the host matrix material. The effect of a thin, rigid cover plate was also examined in this study. Measurement results from in-water acoustical evaluation of a series of 25.4 cm X 25.4 cm panels of these 1-3 composite samples are presented. The transmitting voltage response, free-field voltage sensitivity and directivity pattern of each panel were shown as a function of frequency. The effect of underwater explosive shock was also investigated, and it was found that neither the acoustical properties nor the mechanical integrity of the panel structure was adversely affected. These results demonstrated that these new 1-3 piezocomposites are potentially useful for smart skin applications in underwater acoustics.
