Impact of hybrid and non-hybrid Fiber Reinforced Polymers on mechanical performance of concrete

Fiber Reinforced Polymers (FRPs) are widely recognized in construction for their excellent mechanical properties, low weight, and resistance to corrosion. Recent advancements have introduced various types of FRPs, including intraply hybrid composites (IRCs). This study explores the influence of non-hybrid composites (NHC) and IRCs on concrete's structural performance. The research involved three types of NHC (Carbon (C), Glass (G), and Aramid (A)) and three types of IRCs (Aramid-Carbon (AC), Glass-Aramid (GA), and Carbon-Glass (CG)) used to reinforce concrete specimens of various shapes and sizes. Experimental testing was conducted on 21 cylindrical specimens (100 x 200 mm), 12 cylindrical specimens (150 x 300 mm), 21 prismatic specimens (50 x 50 x 200 mm), 21 cubic specimens (150 x 150 x 150 mm), and 9 small cubic specimens (50 x 50 x 50 mm). The tests included assessments of flexural strength, compressive strength, modulus of elasticity, Poisson's ratio, tangent modulus, and secant modulus. The findings indicate notable enhancements in the mechanical properties of concrete reinforced with both NHC and IRCs, offering valuable insights into their effectiveness in improving concrete performance.
