dc.description.abstract |
Glass transition temperature (Tg) of the bond between CFRP and steel influences on the service and
fire performance of strengthened members. A total of eighty-two CFRP/steel double strap joints were
prepared and tested under elevated temperature. They were cured under a range of elevated
temperature conditions in the control laboratory environment and in the open environment which is
practically feasible in large civil engineering structures. The test results showed a similar trend of
reductions in the bond strength, Poisson’s ratio and Elastic modulus of CFRP/steel joint with the
exposure to the elevated temperature. More than 50% reduction in the Poisson’s ratio, elastic modulus
and the bond strength was noted when the bond line temperature exceeds Tg + 15 0C, irrespective of
the curing time and curing conditions. Initial elevated temperature curing also causes for shifting the
curves in the right-skewed direction. A significant increase in Tg of bond was noted with 4 hours
initial curing at 75 0C, i.e. Tg +20 0C. |
