Abstract

Concrete canvas is a composite material made with three-dimensional spacer fabric, which is manufactured by impregnating the fabric with cementitious materials. Concrete canvas has weaknesses in its mechanical properties including tensile strength. Strengthening concrete canvas with Fiber-reinforced polymer (FRP) materials can effectively improve its mechanical properties, particularly its tensile strength. Therefore, this study focuses on examining the impact of using FRP polymers to enhance the tensile properties of concrete canvas. Three types of fibers, namely Glass Fiber Reinforced Polymer (GFRP), Carbon Fiber Reinforced Polymer (CFRP) and Aramid Fiber Reinforced Polymer (AFRP; known as a Kevlar fiber) in various layer configurations, both warp and weft, were utilized to reinforce concrete canvas under tensile loading. The test results demonstrate that the use of FRP fibers significantly enhances the mechanical properties of concrete canvas. Specifically, single-layer glass fibers lead to considerable growth and reinforcement with carbon and Kevlar fiber layers results in more than five to seven times improvement in tensile strength compared to control concrete canvas.
