Elastomeric Materials for Acoustical Applications
Final rept. 1982-1986
NAVAL RESEARCH LAB ORLANDO FL UNDERWATER SOUND REFERENCE DETACHMENT
Pagination or Media Count:
A background discussion of polymer viscoelasticity is given. Methods of polymer characterization are discussed. Factors in the compounding and vulcanization of elastomeric materials which affect end-product performance are also discussed. General information and cure systems are discussed for a number of different classes of rubber materials. Dynamic mechanical properties of a number of elastomeric materials are graphically presented. Compounding recipes and cure conditions are included, as well as the static physical 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 trade-name cross-indexing, are also incorporated into this work. Additionally, an appendix on acoustical coupling fluids is included. This lists many of the fluids currently in use. Physical properties of interest, such as dielectric constant and electrical resistivity, as well as thermodynamic properties where available are included. Keywords Adhesion Butyl rubber Chlorobutyl rubbers Ethylene-propylene-diene-monomer Fluorocarbon rubber Natural rubber Neoprenes Acrylonitrile rubber Polyurethanes.
