N2 - A full factorial design is performed to investigate a sandwich structure consisted of Piassava fibre laminates as face sheets and epoxy-based honeycomb cores containing eucalyptus sawdust and cement particles. A three-point bending test is used to evaluate the composite structure. The composite setup which achieves higher flexural modulus and strength is used as honeycomb core material. Finite element models are developed to predict the failure and the elastic flexural properties of the sandwich panels. The validated FE model is used to perform a parametric analysis identifying the effect of geometric variations on the flexural performance. The results reveal that the constructive parameters significantly affect the core shear stress, facing stress, flexural stiffness and strength in different ways and intensities.
