ELASTOMERIC SEISMIC ISOLATOR WITH HIGH DAMPING CAPACITY AND MANUFACTURING METHOD THEREOF

摘要

ABSTRACT ELASTOMERIC SEISMIC ISOLATOR WITH HIGH DAMPING CAPACITY AND MANUFACTURING METHOD THEREOF A process for manufacture of elastomeric seismic isolator (10) comprises of the steps of: - preparing a steel mould box with the required dimensions so as to obtain the final product of elastomeric isolator; - stacking the elastomeric vulcanizate sheet (1) and the composite layer of Nitowrap EP (CF) carbon fibre system(2, 3) alternately in the mould box starting with the elastomeric vulcanizate sheet (1), this process being continued until the required height of the elastomeric isolator is obtained, ensuring that the final layer is composite elastomeric vulcanizate (1); and - vulcanizing the mould box with a pressure of 100 Kg/cm2 at 140ºC and keeping it first for 2½ hours for curing and then keeping the vulcanized Isolator on a wooden block for 72 hours.
