Notes:
This research is aimed to fabricate glass fiber/epoxy nanocomposites containingorganoclay as well as to understand the organoclay effect on the in-plane shear strength of thenanocomposites. To demonstrate the organoclay effect, three different loadings of organoclay, weredispersed in the epoxy resin using mechanical mixer followed by sonication. The correspondingglass/epoxy nanocomposites were prepared by impregnating the organoclay epoxy mixture into the dry glass fiber through a vacuum hand lay-up process. Off-axis block glass/epoxy nanocomposites were tested in compression to produce in-plane shear failure. It is noted only the specimens showing in-plane shear failure mode were concerned in this study. Through coordinate transformation law,the uniaxial failure stresses were then converted to a plot of shear stress versus transverse normal stress from which the in-plane shear strength was obtained. Experimental results showed that the fiber/epoxy nanocomposite exhibit higher in-plane shear strength than the conventional composites. This increased property could be ascribed to the enhanced fiber/matrix adhesion promoted by theorganoclay
