This work reports on the static mechanical and modal analysis by free vibration response of hybrid natural fiber reinforced polymer composites. Modal analysis may predict the failure of structures prone to dynamic loading conditions. The composites were compression molded using recently identified short Sansevieria cylindrica fibers and coconut sheath mats in a polyester matrix. The study focused on the effect of the stacking sequence and fiber chemical treatment (alkali and silane) on the composite properties. Hybridization of coconut sheath and Sansevieria cylindrica fiber significantly enhanced all properties compared to single-fiber composites. For all composites (pure or hybrid), the increase in mechanical strength and natural frequency was noticed after chemical treatment. The trend in mechanical strength followed: untreated
