Description
Summary:Recently, fiber reinforced plastics have found applications in civil engineering. Owing to their mechanical properties, these materials have replaced steel and steel plates for external crack repairs in deteriorated structures. Fiber reinforced plastic sheets can be fixed to the structural parts in need of repair, using suitable adhesives. In this article, a new clamping system is introduced that simulates the actual cracking effect. Carbon fabric and its reinforced epoxy laminated composite material are used to join together two parts of a sand-cement mixture by an adhesive at three different gage lengths. Upon the effect of cracking, the performance of the adhesive joint is found to act differently with each material. The three-layer laminated composite is found to act better than the fabric. Each gage length shows a different joint strength.
