Statistical Creep Failure Time of Unidirectional CFRP under Compression Loading
Abstract
This paper is concerned with the statistical prediction of compressive creep failure time in the longitudinal direction of unidirectional CFRP based on the viscoelasticity of matrix resin. The compressive and tensile creep failure times of unidirectional CFRP were statistically predicted by substituting the compressive and tensile static strengths measured at various temperatures and viscoelastic behavior of matrix resin in our proposed formulation. Then the compressive and tensile creep failure times of unidirectional CFRP at a constant load and temperature were measured experimentally for comparison with the predicted ones. The characteristics of statistical compressive and tensile creep failure times of unidirectional CFRP were compared with each other from the difference of failure modes in the compression and tension loads.
