This paper presents the results of an experimental characterization of a glass fibreepoxy composite. The behavior of the traditional twophase composite has been compared with the one of a new threephase composite where the epoxy matrix was modified by addition of a 3 weight fraction of montmorillonite nanoparticles. Two different types of nanoclays, Cloisite® 30B and RXG7000, produced by Southern Clay Products Inc., have been considered. Threepoint bending tests, both monotonic and cyclic, were carried out. A strong reduction of the ultimate flexural strength upon nanomodification has been observed in quasistatic tests. Fatigue tests yielded a smaller strength loss. In both quasistatic and fatigue tests a more pronounced tendency to delamination has been noticed in threephase composites, especially in the case of 30B nanoclay, with respect to the standard twophase glass fiber composite.
