Notes:
This research focuses on the fabrication of glass fiber/epoxy organoclay nanocomposites aswell as on the investigation of organoclay effect on transverse tensile strength and in-plane shearstrength of the nanocomposites. To demonstrate the organoclay effect, three different loadings oforganoclay were dispersed respectively in the epoxy resin using a mechanical mixer followed bysonication. The corresponding glass/epoxy nanocomposites were produced by impregnating dry glassfiber with organoclay epoxy compound via a vacuum hand lay-up procedure. For evaluatingtransverse tensile strengths, the unidirectional coupon specimens were prepared and tested in thetransverse direction. Results indicate that with the increment of organoclay loadings, the glass/epoxynanocomposites demonstrate higher transverse tensile strength. On the other hand, the in-plane shearstrengths were measured from [± 45]s laminates. It is revealed that when the organoclay loadingsincrease, the in-plane shear strength of glass/epoxy nanocomposites also increases appropriately.Scanning Electron Microscopy (SEM) observations on the failure surfaces indicate that the increasingcharacteristics in transverse and in-plane failure stresses may be ascribed to the enhanced fiber/matrixbonding modified by the organoclay
