Aim of this work is to investigate the feasibility of using a natural and inexpensive filler obtained by grinding the culms of Arundo Donax as reinforcement of epoxy resins. The effect of the content and size of Arundo Donax fillers on static and dynamic mechanical properties was evaluated showing that the composites exhibit higher tensile moduli, comparable flexural moduli and lower strength properties in comparison to the neat resin. Moreover, changes in the storage and the loss moduli only above the glass transition temperature (i.e. in the rubbery region) were found while neither significant shifts of tand peaks to higher temperatures nor reductions in the peak height of the composites were also observed.To better understand the influence of Arundo Donax filler on the morphology of the composites, the analysis of the fractured surfaces using a scanning electron microscope and the assessment of void content were carried out. The results of this study shown that a new natural filler may be considered as possible reinforcement of epoxy composites useful in semi-structural applications.
