Epoxy composites containing montmorillonite (MMT), laponite (LAP), and halloysite nanotubes (HNT) are prepared using two different dispersion techniques: sonication and high energy ball milling. The mechanical properties of the composite materials are monitored as a function of the type of clay particle/geometry and processing technique. The materials are characterized by X‐ray diffraction, microscopy techniques, parallel plate rheometry, and mechanical testing. Experimental results present clear evidence that sonication has led to better nanoparticle dispersion. The results also indicate that the composites manufactured via sonication exhibited higher ductility.
