FRP Reinforcing bars — designs and methods of manufacture (Review of Patents)

  • Published:
Mechanics of Composite Materials Aims and scope

It is been suggested to devide all FRP reinforcing bars into three groups in accordance with the method used for establishing a bond between the core of the bars and concrete. Patents related to each group are cited and briefly described. At the end of the paper, ideas proposed in the patents are discussed. Problems connected with a practical implementation of FRP reinforcing bars will be considered in the next paper.
