Introduction A number of materials may be used to strengthen and stiffen reinforced concrete. For instance, the use of carbon fiber in the form of CFRP (Carbon Fiber Reinforced Polymer) has gained popularity rapidly in civil engineering for the last two decades. Being a cost-effective alternative to steel due to its high strength to weight ratio, carbon fiber has found a number of applications in the construction industry (Roberts, 1989). One of the common applications of carbon fiber in structures is retrofitting, where the main aim is to strengthen existing structures. In addition, carbon fiber related composites are used as a substitute to steel for the purposes of pre-stressing. In all applications, carbon fiber improves flexural, shear and tensile strengths of concrete leading to increment of the overall structural integrity. According to Zhou et al. (2013), CFRP is a reliable strengthening element in civil engineering structures. However, the research revealed that the probability of failure with such a beam would be relatively high due to premature debonding. To counter the failure mode, improvement on bonding characteristics has become imperative through restriction of displacement by sliding. In effect, Zhou, et al. (2013) utilized a technique referred to as FRP-FHB (Fiber Reinforced Polymer – Friction Hybrid Bonding), in which 2 reinforcing fibers are linked into a single network matrix with better bonding characteristics. Carbon Fiber Reinforced Polymer and Epoxy Resins According to the postulation made by Al-Amery and Al-Mahaidi (2006), appliances of CFRP strands prevent failures in debonding. Al-Amery and Al-Mahaidi (2006) explained that this prevention arises from the provision of additional strengthening strategies on CFRP sheets. The stand minimizes interface slip placed at the center of sheets and concrete. Additionally, Riyadh identified that longitudinal strain is variant in accordance to tally of layers permitting a differential strain to traverse the CFRP matrix. Saleh et al. (2009) established the relationships that modified a strategy to calculate interfacial bond stress. According to Braz and Soc (2006), composite materials based on carbon fiber and epoxy resin have gained popularity in engineering applications, such as aircraft structural framework manufacture, due to their high strength to weight ratio. In addition, epoxy resins are resistant to creep, chemical action and breakage. Moreover, epoxy resins have been found to exhibit good adhesion characteristics with most of the common engineering substrates. However, a major limitation of epoxy resins (ERs) is their high brittleness after passing through the curing process. However, addition of a small percentage of liquid rubber has been found to improve ERs’ fracture properties that include fatigue resistance and fracture toughness. Although the addition of reactive rubber improves fracture properties of ERs, it is worth noting that the molecular weight of the selected rubber is a critical factor. In application, only rubber with relatively small molecular weight should be used. Mainly, excessive addition of denser materials in the ER matrix may result into high viscosity that would lead to low process ability. A possible light-weight rubber that can be employed in this ca
