Abstract
In this study, fatigue properties of unidirectional Arenga Pinnata fibre reinforced epoxy composites have been investigated under tension-tension fatigue loading. Composites were made at 25% by Arenga Pinnata fibre weight contents using hand lay-out technique. Tensile test was performed prior fatigue loading evaluation. The composites where then were cycled between 90%, 80%, 70% measured from ultimate tensile stress (UTS), with 10 Hz of frequency and stress ratio of R at 0.1. Tensile results indicated that the composites resist to deformation and this reaction denotes that the composites are a brittle material. Fatigue life of composite was improving as the cycled stress decreases. The fatigue resistance were calculated by employing analytical expression and compared with relevant fatigue data.
