Rebar made from poly urethane fiber reinforced plastic to be used in concrete as a tensioning device

摘要

This invention is aimed to a new revolution in reinforced concrete structure. The invention is related to the process of manufacturing a new type of Rebar made from pu fiber reinforced plastic and Glass-reinforced plastic consist of fibers of polymer. The invented pu fiber rebar will be used in concrete structure as a tensioning device. The invented pu fiber rebar will become an idea! option to the steel rebar used in concrete. The invented pu fiber rebar is corrosion proof. Further, in situation of short circuit, the pu fiber rebar cannot supply electric current. The inventedpu fiberis light weight and easy to install during the construction process. Using the invented pu fiber rebar concrete construction will become easy and less expensive with compare to the steel rebar. The inventedpu rebar will also increase the healthy life of concrete structure for longer period of time without repairing and maintenance.
