Abstract
An epoxy-phenolic resin suitable for use as a composite matrix was reinforced with modified nanoclay (montmo- rillonite type). Characterization by x-ray diffraction and transmission electron microscopy (TEM) demonstrated that inter- calated nanocomposites were formed with an inter-gallery distance of approximately 10 nm. The influence of nanoparticles on tensile strength and modulus, fracture toughness, and impact toughness was measured and compared with the unrein- forced polymer. The results revealed that the maximum enhancement in stiffness and toughness was achieved with 2.5 wt% filler content. The enhancement in toughness behavior was attributed to the activation of multiple energy-dissipating dam- age mechanisms in the nanocomposites.
