Thermoplastic carbon fiber reinforced polymer tapes in cementitious and polymer concretes

Abstract Deterioration of infrastructure is recurring phenomena and requires rapid resurrection, it is always better to be early than late. To keep up and improve, American infrastructure requires rapid reforms. Building materials that are resilient and innovative must govern the existing counterparts. Fiber Reinforced Polymers (FRP) have proven itself to be adaptive, lightweight, having high tensile strength and corrosion proof, perfectly suitable for the current weathering defects that rose in civil infrastructures. Under FRP the 3D printed thermoplastic woven like a loom where the interlocking of two directional fiber layers is perpendicular to each other, could be potentially used as reinforcement, which this paper primarily focuses on. Typically, Carbon FRP (CFRP) tapes are considered CFRP to have greater tensile strength and have higher repulsive property towards the chemicals. The tapes are classified as lattice, which is mainly the tape arrangement. Also, this paper incorporates the interaction between the 3D printed CFRP and the concrete (plain cement Concrete, ultra high-performance concrete (UHPC) and polymer concrete and observe its flexural properties) beams. The former study related to 3D printed thermoplastic material using as a reinforcing material is limited. Hence, it is believed that the results from the paper aim to establish new design criteria and standards, providing valuable insights for future engineering applications and infrastructure projects. Results show the ductility behavior of the UHPC beam with the CFRP tapes were significant compared to the other beams. The ductility recorded was >20 mm. The failure pattern showed the tension failure i.e. the CFRP tapes failure before the concrete rupture for each type of concrete.
