Carbon Fibre Reinforced Polymer Strengthening for Concrete Beam Wilson Handoko School of Materials Science and Engineering, The University of New South Wales, Sydney, NSW 2052, Australia Abstract Fibre Reinforced Polymer (FRP) has been used in many sectors for over 20 years as it has excellent properties in terms of high tensile strength-to-weight ratio, corrosion resistance, durability, mouldable and good thermo mechanical properties. These excellent properties lead to the low maintenance cost for alternative construction, automotive, marine to the aerospace industries. This paper will provide the improvement in strength of FRP in which will give a significant change in engineering field and perform better materials to sustain the…show more content…
These fibres are commonly made of the carbon, glass or strong synthetic fibres (aramid) or sometimes it is combined with natural composites such as paper or wood. The composite polymers that are generally used are the polyester, epoxy or vinylester [1]. Furthermore, the composite materials (eg. Concrete Reinforcement), is a new development of technology for construction of buildings, bridges and highways. The lack of tensile strength in the concrete and steel to the coaster weather and seawater pushes the technology to beyond its limit as create new composite such as non-metal reinforcement for concrete structure. Commercially, most composite materials are weaker and less stiff but strong and stiff fibres in a matrix. The main purpose of this paper is the advantage of high modulus CFRP to improve the corrosion resistance, tensile strength of the reinforcement concrete. CFRP can be improved in tensile strength, deflection of structures and flexibility by increase the elasticity of strength modulus rather than steel. Moreover, the extreme environment such as corrosive condition can be prevented with this Fibre Reinforced Polymer benefit, as it is corrosion resistance materials. The compressive strength can be enhanced to approximately 15% compared to the normal strength by adding 1.5% of fibres in the volume; this effects the strain and stress of the compressive strength [2].
