Abstract

In this study, the effect of lattice geometry on the modal response of cylindrical carbon/epoxy lattice structures have been investigated both experimentally and numerically. Two structural geometries of triangular and hexagonal were chosen. Accurate flexible molds were used to manufacture the carbon/epoxy composite samples using polar-winding process. Experimental and numerical investigation of the vibration response of the manufactured samples were analyzed in order to determine the natural frequency and modal response for both triangular and hexagonal lattice structures for simply supported beam conditions. The results obtained from the Numerical model shows a good agreement with experimental results. after validating the numerical model, other supporting conditions like simply -fixed and fully fixed support was investigated Numerically. Results shows that the triangular structure lattice has higher natural frequency than hexagonal structure for all different support conditions.
