Developed the "C-VaRTM method," a reinforcement technology for brace joints in steel structures and carbon fiber repair/reinforcement of steel members, which allows for reinforcement tailored to the substrate within a short construction period.

Our company has developed the "C-VaRTM method" for reinforcing brace joints in steel structures and for repairing/reinforcing steel components, applying the carbon fiber repair/reinforcement technology "on-site VaRTM" developed by Toray Industries, Inc. (Headquarters: Chuo-ku, Tokyo; President: Mitsuo Oya, hereinafter referred to as "Toray"). By appropriately proposing the C-VaRTM method for the repair/reinforcement of steel components, we aim to contribute to the longevity of structures and the maintenance of a safe social environment. The C-VaRTM method is a repair/reinforcement technology that applies the on-site VaRTM method, which involves placing specially processed carbon fiber sheets over the surface of the repair/reinforcement area, sealing it with a film, and injecting resin under vacuum conditions created by a vacuum pump, allowing the resin to impregnate the carbon fiber due to atmospheric pressure. By combining it with CFRP molded plates and other materials, it enables repair/reinforcement for a variety of applications. *: The method called VaRTM (Vacuum assisted Resin Transfer Molding) is applied to adhere CFRP to steel materials, restoring them to the required strength.
