Handbook of Sonar Transducer Passive Materials
Abstract
Difficulties in the engineering applications of elastomeric materials in sonar transducers are discussed. Factors in the compounding and processing of elastomeric materials which affect end-product performance are also discussed. Dynamic mechanical properties of a number of elastomeric materials are graphically presented. Appropriate relationships for calculating such parameters as the sound speed, attenuation, and loss factor from these curves are given. Compounding recipes and cure conditions for the elastomers are included, as well as physical static properties. References to standard test methods (ASTM) are included where applicable. Indices containing names of suppliers of elastomeric materials and adhesives, as well as generic and tradename cross-indexing, are also incorporated into the handbook. Additionally, a section on transducer coupling fluids is included in the handbook. This includes fluids currently in use, as well as those liquids being considered for future use. Physical properties of interest, such as dielectric constant and electrical resistivity as well as thermodynamic properties (where available), are included. (Author)
