Popis:	Our developed accelerated testing methodology (ATM) based on matrix resin viscoelasticity for the long-term life prediction of carbon fiber reinforced plastics (CFRP) was applied to assess the statistical prediction of long-term creep failure time of a carbon fiber/polypropylene unidirectional (CF/PP) laminates under creep bending load. Results show that the statistical long-term creep failure times under an arbitrary constant bending load and temperature for the CF/PP laminates can be easily predicted from the statistical static strengths of the CF/PP laminates measured at several temperatures and the viscoelasticity of matrix PP.
