Abstract
The method of predicting the statistical creep failure time under the tension loading along the longitudinal direction of unidirectional CFRP from the statistical static strengths of this CFRP measured at various temperatures is applied to various unidirectional CFRP with different kinds of carbon fibers. Two kinds of CFRP strands with two kinds of PAN based carbon fibers as specimens for unidirectional CFRP are prepared. The static strengths of these CFRP strands are experimentally and statistically measured at various temperatures. Then the creep failure times of these CFRP strands are predicted statistically using the statistical static strengths based on the predicting method. Finally, the creep failure times of these CFRP strands at a constant load and a temperature are measured experimentally and probabilistically using these CFRP strands for comparison with the predicted ones. Additionally, the predicting method is also applied to two kinds of CFRP strands with two kinds of pitch based carbon fibers.
