We have observed in our previous work that the tensile strength along the longitudinal direction of unidirectional CFRP under constant strain-rate loading is highly time-temperature dependent and obeys the same time-temperature superposition principle with that for matrix resin. We present in this paper a prediction scheme for the tensile strength by making adjustments pertinent to polymer matrix to Rosen's formula for fiber reinforced composite with elastic matrix. The prediction scheme requires the CFRP strength in the glassy region and the shear relaxation modulus of matrix resin. The prediction curve based on the proposed method captured the test data adequately over the wide range of temperatures and loading rates.
