The
carbon fiber
reinforced plastics (CFRP)，which has the great characteristics of inoxidizability, durability as
well as high specific tenacity (unit quality intensity), is among the most
ideal
reinforcement materials. However, If CFRP is used directly in
strengthening building and bridge structures; it can make certain enhancement
to the load, but seldom enhance the rigidity distinctly. Moreover, this way
cannot fully develop the CFRP’s superiority of high strength, and may lead to
component’s debonding
failures. It is indicated by some related experiments
that using
prestressed carbon fiber reinforced plastics (CFRP) technique not
only can effectively improve the rigidity of the reinforced concrete component,
but also can greatly restrain crack development. The reinforced concrete structure
which is reinforced by prestressed CFRP is not easy to appear debonding
failures, and can fully reach its high intensity. It takes less expenditure
compared to other reinforcement techniques also. In conclusion, Reinforcement
technology by prestressed CFRP has wide applicable prospect.
