Abstract:
This paper presents the results of a pilot study, investigating the punching shear characteristics of slabs reinforced with three-dimensional carbon fiber fabric. The three-dimensional carbon fabric is prefabricated from the use of continuous carbon fibers that are impregnated with epoxy resin. Punching shear tests were conducted on four slabs reinforced with the three-dimensional carbon fiber fabric and two slabs reinforced with conventional mild steel reinforcement. The behavior and strength of slabs reinforced with the three-dimensional carbon fiber fabric are described and compared with the results of similar slabs reinforced with conventional mild steel reinforcement.
