The morphology and mechanical property of synthetic zirconium phosphate (ZrP) epoxy nanocomposites were studied. The nanocomposites were characterized using wide angle X-ray scattering and transmission electron microscopy to confirm the exfoliation of the ZrP layer structure in epoxy matrix. The mechanical property and fracture toughness (KIC) of ZrP-epoxy nanocomposites were studied using dynamic mechanical analysis, tensile tests, and single-edge-notch three-point-bend test methods. The rubbery plateau modulus of the surface modified ZrP-epoxy nanocomposite (M-ZrP-Neat) is found to be about 4.5 times higher than that of the reference epoxy. The tensile modulus of the M-ZrP-Neat nanocomposite is increased by 50% with only 1.9 vol% of ZrP addition. However, the elongation at break was decreased drastically.
