Such the mechanical properties, which are dependent upon the time and temperature, as the transversal relaxation modulus, the longitudinal and transversal tensile, compressive and flexural strengths, of unidirectional CFRP are investigated in connection with epoxy resin of its matrix. These mechanical properties of CFRP show thermo-rheologically simple behaviors in same manner as the mechanical properties of matrix resin. And them the obvious quantitative relations between these mechanical properties of CFRP and that of matrix resin are obtained.
Based on these results, new selection rule of the matrix resin for unidirectional CFRP which have required mechanical properties at arbitrary time and temperature are proposed.
