Introduction Polymer matrix composites have brought the possibility of achieving important energy reductions into the full life cycle of these materials, especially in transportation applications where low weight and high strength and good corrosion resistance are required [1].
One of main aspects currently limiting the wide application of the composite materials on a mass production scale is their ability to be effectively joined together.
Fig. 1: Fusion bonding of thermoset composite using co-cured thermoplastic surfaces Experimental Materials used for current study were carbon-fibre plain weave fabric reinforced epoxy prepreg and PSU film with a thickness of 77mm.

In this methodology, the FRP reinforcement is installed into slits cut into the concrete cover using cement mortar or epoxy as bonding materials.
Concrete unit The Solid65 unit in ANSYS is a three-dimensional solid element, specially developed as concrete, rock, and other materials’ simulation.
It can simulate the concrete materials specific to cracking, crushing and other mechanical phenomena, has a good pre-defined criteria for the destruction of concrete.
Constitutive materials and related parameters The CFRP rebar constitutive AS CFRP bar at the bottom of the tension zone, mainly bearing longitudinal tension, it will be simplified for isotropic linear elastic material.
The developed FE model considers concrete material’s nonlinearities in tension and compression, yielding of steel reinforcement, cracking of filling materials, bond-slip action, and cohesion between the filling material and concrete interfaces.
