I am not sure I understand your question fully well. Are you asking about the benefits of CFRP patch work or the tensile or shear strength of the CFRP patch work? If it is about the former, then I feel the justification 'carbon fibre–epoxy is close to the nature of wood' in your paper adequately answers your question. On the later, carbon fibre is widely known to have high tensile strength; and the longer and more proximal they are in a composite with adequate interfacial bonding the higher their tensile strength. Thus, longer highly oriented  carbon fibre along (near parallel to) the axis of strain in epoxy or which ever matrix would be expected to record high tensile strength. Shear strength of the carbon fibre would depend on the average strength and width of the carbon fibre-epoxy bonding interface, the degree of randomness of the carbon fibre in the matrix and the bending strength of carbon fibre in epoxy or which ever matrix for that matter. Thus, if you are looking for specific tensile, shear and bending values you would have to conduct experiments using highly oriented and fairly random samples of CFRP patch and standard tests to determine.     

Dear sir,

Actually i have asked two question.but the way i asked is confusing,sorry.
