Project Summary

The objective of this study is to study the durability of thermoplastic composite (TC) rebars. The end-use of thermoplastic rebars is as reinforcements in concrete structures. This research work focuses on the effects of moisture, alkaline exposure, and seawater wetting and drying cycles of thermoplastic rebars manufactured using CFM technology. Thermoplastic rebars will be subjected to accelerated ageing conditions at elevated temperatures. The change in mechanical properties of the thermoplastic rebars with time will be evaluated using tension and compression. In addition, changes in thermal and physical properties will be evaluated. The accelerated durability results will be summarized and used to develop a comprehensive approach to predicting long-term mechanical properties of the thermoplastic rebars for designing concrete structures.
