FRP strength member/Fiber Reinforced Plastic FRP Rod
FRP Rod strength member is to use epoxy resin as foundation combined with the strength of glass fiber through pultrusion technology to produce a new type of high performance non-metallic composite material which is used to make various optical fiber cables.
