Investigation on the Static and Fatigue Failure of Bi-Directional Composite Pipes
The process of filament winding is particularly suited to the manufacturing of composite pipes. This paper first describes the overall process and its advantages for composite structures. Particular attention is devoted to bi-directional pipes [+j, -j]n. The static behaviour exhibits damage and plastic phenomena depending on the loading and stacking sequence. In the main part of the paper we focus our presentation on [+55, -55]n. The failure mode under tensile-internal pressure loads of bi-directional pipes is described, as well as their fatigue behaviour with the effect of several parameters (such as frequency) on the lifetime and the kinetics of damage. In particular, this paper shows that the effect of frequency is related to two phenomena: temperature and fatigue-creep coupling, which have opposing action on the lifetime.
