Abstract:
Rubber has become an indispensable material in Ocean technology.
Rubber components play critical roles such as sealing, damping,
environmental protection, electrical insulation etc. in most under water
engineering applications. Technology driven innovations in electro acoustic
transducers and other sophisticated end uses have enabled quantum jump
in the quality and reliability of rubber components. Under water electro
acoustic transducers use rubbers as a critical material in their construction.
Work in this field has lead to highly reliable and high performance
materials which has enhanced service life of transducers to the extent of 1015
years. Present work concentrates on these materials. Conventional
rubbers are inadequate to meet many of the stringent functional of the
requirements. There exists large gap of information in the rubber
technology of under water rubbers, particularly in the context of under
water electro acoustic transducers. Present study is towards filling up the
gaps of information in this crucial area. The research work has been in the area of compounding and characterisation of rubbers for use in under water electro acoustic transducers. The study also covers specific material system such as
encapsulation material, baffle material, seal material, etc. Life prediction
techniques of under water rubbers in general has been established with
reference to more than one functional property. This thesis is divided into 6 chapters.
