Manufacturing of Frp Rebars by a Combined Filament Winding and Pultrusion Process
Fiber reinforced polymer (FRP) composites are being applied in aerospace, transportation, construction, and a variety of other industries. Considerable interest has been generated recently in the use of FRP rebars to overcome corrosion problems. The ductility of composite rebars has been a major concern. The lack of ductility can be solved by using a hybrid rebar with unidirectional and helical fibers. This work presents the manufacturing aspect of hybrid FRP rebars with embedded fiber optic sensors using a combined filament winding and pultrusion process. A three dimensional heat transfer analysis is conducted to find the die temperature distribution in the pultrusion process. Fiber optic sensors can be used as strain measuring devices for structural health monitoring. Test results of the FRP rebars are presented to demonstrate the pseudo-ductile behavior.
