Thermoplastic CFRP Sheet Method | A Paper on the Bending Reinforcement Performance of RC Beams

Balancing shortened construction periods and reliability. Based on static loading experiments of RC beams, the reinforcing effect and adhesion performance of thermoplastic CFRP sheets are explained with detailed data.

We provide the latest research materials focused on the urgent themes of "shortening reinforcement construction periods" and "simplifying construction" in addressing infrastructure aging issues. This paper demonstrates solutions using new materials to tackle the challenges faced by conventional methods. ■Contents of this paper Demonstrated reinforcement effect: Experimental evidence shows that thermoplastic CFRP sheets possess bending strength and crack dispersion effects equal to or greater than those of conventional carbon fiber sheets. Quantitative basis for process reduction: The newly developed adhesive resin simplifies processes such as surface correction, explaining a mechanism that can reduce construction time by approximately 40%. Safety of joint construction: Verification that performance can be maintained at levels equivalent to those without joints, even when joints are located at points of concentrated stress. Adhesion strength exceeding design guidelines: Data supports a robust adhesion performance with interfacial peel energy significantly exceeding design values. Please check the comprehensive details of this highly practical reinforcement technology that enables thermal bending processing and overlapping joints on-site. *The full text can be viewed by downloading the catalog.
