*WINNER* Fatigue Analysis of Carbon Fibre Reinforced Composite Components Manufactured by Fused Filament Fabrication

Abstract

The development of fiber composites in recent years has been remarkably strong, owing to their high performance and durability. The fatigue behavior of components is an important knowledge, as cyclic loading is a common feature of most engineering applications. The scope of this paper is to present the fatigue properties of carbon fiber-reinforcing Polyethylene terephthalate glycol (CF-PETG) components manufactured by FFF with a focus on different printing orientation. Simplify 3D and stacker S2 are used to slice and to manufacture the components respectively. The printing orientation and direction used are XY-00, XY 450, XY 900 and YZ 900. Fatigue testing is carried on 70% of Ultimate Tensile Strength (UTS). Analysis of Variance (ANOVA) is used to analyze the data obtained from the fatigue test.
