FRP reinforcement bar is made from high strength glass fiber
reinforced with vinyl ester resin. The core of the rebar has all
the reinforcing fiber (70% by weight ) along the length of the bar
for maximum strength. A helical recess in the surface of the rebar
is created in the production process which does not damage the core
fiber and is sufficiently deep to give a key to enable the concrete
to have a mechanical grip on the rebar.
The choice of vinyl ester resin for the rebar is important.
Extensive research work has shown that polyester resin does not
have the necessary long term resistance to the corrosive chemicals
in the concrete while rebar made with vinyl ester resin gives a 50
year service life when used in accordance with the recognized
(1)Explosion-proof, anti-static: there is no sparks when cutting,
and extremely beneficial for roadway safety construction.
(2)Strong tensile strength: the strength of carrying capacity is
(3)Easy to operate: easy to use in tight spaces, such as tunnels
(4)Easy to cut: it can protect the cutting machine
(5)Light-weight: Weighs is only 1/4 of the same specification
steel. Thereby reducing the transportation costs and making it
easier for construction
(6)Anti-aging, acid and alkali, corrosion resistance, and long
(7)Strong material combination: coefficient of thermal expansion is
more close to cement compared with steel so the bond stress is more
stronger between FRP geosynthetics and concrete.
(8)Strong designability: stable elasticity modulus, stable size
under thermal stress, bending and other shapes can be any
(9)Strong performance of through waves: it’s a kind of non-magnetic
materials, and it do not need demagnetize in concrete structures of
non-magnetic or electromagnetism.
(1)Reinforcement for subgrade strengthening
(2)Anticorrosive reinforcement is used for pier and seawall.
(3)Building reinforcement is used for medical.
(4)Subway platform reinforcement
(6)Smelting bottom reinforcement
(7)Military build body reinforcement
(8)Temporary basis reinforcement
