The Development on Hybrid FRP Rod and Its Tensile Properties

Hybrid FRP Rod의 개발과 인장특성

Utilization of new lighter materials, more tough and durable than existing materials, is getting larger in recent constructions. FRP, stronger and lighter than present materials, can be formed in various shapes and has high durability, which makes it more profitable as a new material in construction fields. However, effort to use FRP in real construction is toddling and FRP is used primarily as reinforcing material in connote structure. We are about to develop Hybrid FRP Rod for the development of advanced construction material which is based on IT, by Hybridization of HIP, spotlighted as new construction material, and optical sensor in smart measurement. Beforehand, it is required to fully understand the properties of tension test operated in Hybrid FRP Rod. For this, a specimen was made by hybridization of FRP Rod and FBG sensor. Strain of Hybrid FRP Rod was measured comparing electric sensor and FBG sensor.
