GRP rebar is a kind of composite material widely used in my country. At present, the GRP rebar used in China is mainly an integral fully threaded steel bar. The structure of this steel bar is composed of a rod body, a tray and a nut. The tray and the nut are also generally made of FRP, mainly to avoid sparks when the shearer is cutting. So, what is the application prospect of GRP rebar in my country's engineering?

At present, the quality of GRP rebar can already meet the support requirements of many roadways. At the same time, it has many advantages such as low price, light weight, corrosion resistance, and easy cutting, so it undoubtedly has broad application prospects. The successful development of the fully threaded GRP rebar further improves the quality of the rebar. The rebar production method is simple and reliable, and is bound to become the mainstream product in the GRP rebar.
Although GRP rebar has broad application prospects, FRP material has its own defects, such as poor shear, torsion, and bending resistance, which cannot be overcome by simply changing the structure or production process of the steel bar. The scope of its application will still be limited.
