Özet

This article introduces a design procedure to find the optimum fiber orientations of carbon/epoxy composite laminates for
fatigue life advancement. The approach incorporates a fatigue failure tensor polynomial model and employs a hybrid
algorithm, combining particle swarm optimization and sequential quadratic programming. Firstly, material properties of
quasi-static and fatigue of the carbon/epoxy composites, fabricated by the vacuum-assisted resin transfer molding method,
were determined to be used in the model. Various design problems involving two optimization scenarios were then solved
using the hybrid algorithm. The algorithm’s performance was also evaluated by specific test problems, confirming its speed
and robustness. The optimally fiber-oriented carbon/epoxy composite laminates having maximum fatigue lives were
obtained for many critical in-plane cyclic loading cases. To validate the proposed design procedure, two optimum designs
were experimentally verified under uniaxial loading conditions. The results indicated a good correlation between the
estimated fatigue life of the optimally designed laminates and experimental data. This methodology offers a promising
approach for the design of carbon/epoxy composite laminates with superior fatigue strength, particularly significant in
specific industrial applications.
