Prediction of Fatigue Life for CFRP/Metal Bolted Joint under Temperature Conditions

Abstract

In 1997, we proposed a prediction method of fatigue failure load for polymer composite structures under an arbitrary frequency, load ratio (minimum load/maximum load), and temperature from the data measured by constant elongation-rate (CER) tests under various temperatures and loading rates, and by fatigue tests at a single frequency under various temperatures. In this paper, tensile CER and fatigue tests of CFRP/metal bolted joint were conducted for various temperatures and loading rates. The applicability of the proposed method was experimentally proven for the tensile fatigue failure load for this CFRP/metal bolted joint.
