Desing, Manufacturing, and Characterization of Fiber Reinforced Shape Memory Polymer Rebars

The objective of this one-year project is to design, manufacture, and 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 will be 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 pre-cast concrete (PC) construction, so that prior programming can be coupled with construction. It is expected, the FRSMP rebar, in addition to its advantages similar to conventional fiber reinforced polymer rebar such as high specific strength/stiffness and corrosion resistance, will help close cracks in the tension zone of PC beams and provide negative bending moment, extending the service life of PC beams.
