Abstract

An advanced accelerated testing methodology (ATM-2) for long-term life prediction of carbon fiber reinforced plastics (CFRP) laminates exposed to actual loading with a general stress and temperature history is proposed based on the conventional accelerated testing methodology (ATM-1) established for the long-term life prediction of CFRP laminates exposed to stress and temperature. The most important condition for ATM-1 is that the time–temperature superposition principle held for the viscoelastic behavior of matrix resin holds also for the static, creep, ...
