Abstract:The objective of this one-year project was to design, manufacture, and tension program fiber reinforced shape memory polymer (FRSMP) rebars, and test their shape memory effect. Unidirectional glass fiber tow and ultraviolet (UV) curing shape memory polymer with high glass transition temperature will be selected to fabricate the FRSMP rebars. Two types of FRSMP rebars manufactured and tested, one is straight rebar, which will be subjected to tension programming, and the other is curved rebar, which will be programmed by bending. The rebar programming can also be coupled with pre-stressing or post-stressing in precast concrete (PC)construction, so that prior programming can be coupled with construction.
