New Composite Wedge System forPrestressing Fibre-Reinforced Plastics

Composite Wedge System


Carbon fibre reinforced plastics (CFRP) have been used for many years in the aerospace, aircraft construction and other high technology industries because of their unique characteristics. The exceptional factor in the case of CFRP rods or lamellas is their high tensile strength and high Young’s modulus combined with a low dead weight. The tensile strength and/or the yield point of CFRP is about 10 times greater than that of general structural steels and at a fifth of the dead weight. The fact that it does not have to be protected from corrosion like steel is also a major advantage. CFRP is very resistant to chemical attack. This is of particular importance in the case of slim components or components with only a thin concrete cover, where there is a high level of attack from salt or other chemicals.
