In order to overcome the shortcomings of FRP rebars in terms of their bending after the pultrusion process, the possibilities of using a thermoplastic matrix instead of a thermosetting have been extensively studied lately. The integration of these novel materials into the production process has raised important questions regarding both short- and long-term mechanical properties, durability, and performance under extreme thermal conditions, corresponding to the accidental fire situation. To this aim, and as part of the TOP-Crete project, an experimental campaign has been conucted. Glasspree TP FRP bars based on Elium® resin have been tested under transient temperature conditions across different load levels. Based on the obtained results, a temperature-dependent strength curve has been established. Additionally, the performance of these thermoplastic FRP bars was compared with that of traditional glass-fiber-reinforced polymer (GFRP) bars utilizing a thermosetting matrix. Dependence between the retention strength of TP FRP and elevated temperatures ranging from 200 °C up to 700 °C has been presented.

摘要

In order to overcome the shortcomings of FRP rebars in terms of their bending after the pultrusion process, the possibilities of using a thermoplastic matrix instead of a thermosetting have been extensively studied lately. The integration of these novel materials into the production process has raised important questions regarding both short- and long-term mechanical properties, durability, and performance under extreme thermal conditions, corresponding to the accidental fire situation. To this aim, and as part of the TOP-Crete project, an experimental campaign has been conucted. Glasspree TP FRP bars based on Elium® resin have been tested under transient temperature conditions across different load levels. Based on the obtained results, a temperature-dependent strength curve has been established. Additionally, the performance of these thermoplastic FRP bars was compared with that of traditional glass-fiber-reinforced polymer (GFRP) bars utilizing a thermosetting matrix. Dependence between the retention strength of TP FRP and elevated temperatures ranging from 200 °C up to 700 °C has been presented.
