Reinforcement of structures using the FORCA Tow Sheet method

The FORCA Tow Sheet method is a method to reinforce concrete structures using FORCA Tow Sheet (carbon fiber sheet) which was developed by Tonen Corporation and is currently available from Nippon Steel Composite Co., Ltd. The method won a 'Fine Technology Prize' from the Japan Society of Composite Materials in 1997. In this method, the carbon fiber sheet is bonded to the concrete surface with an ambient temperature cure resin. The use of this method to repair or reinforce concrete structures has spread rapidly as it requires less time, reduces the cost of incidental work, and subsequently cuts labor costs through improvements in work efficiency.
