Determining the interphase thickness and properties in polymer matrix composites using phase imaging atomic force microscopy and nanoindentation

The effect of graphene oxide and its oxidized debris on the cure chemistry and interphase structure of epoxy nanocomposites

“…The OD clearly has a major role to play in the performance of nanocomposites by acting as a compatibilizing surfactant which is beneficial in producing nanocomposites with a good dispersion and a toughened interface between GO and a polymer matrix [60]. It is well known in carbon fibre composite technology that maximizing the reaction between the graphite surface and epoxy resin, while increasing the modulus, does not lead to the highest fracture toughness [61]. The modification of the epoxy-GO interphase by the OD to lower the crosslink density could contribute to the reported higher nanocomposite toughness.…”

Characterizing and Modeling Mechanical Properties of Nanocomposites-Review and Evaluation

“…This technique uses the same principle as microindentation, but with much smaller probe and loads, so as to produce indentations from less than a hundred nanometers to a few micrometers in size. During the past dozen years or so, it has been widely used in measuring the mechanical properties of various nanocomposites [14][15][16][17][18][19][20][21][22][23][24][25] and human enamel and dentin [26][27][28][29][30][31][32][33][34][35][36][37][38].…”

Effects of γ-ray radiation grafting on aramid fibers and its composites

“…Nanoindentation testing is an effective and relatively straightforward approach to accurately measure the interfacial mechanical properties in composites on the nanometric scale [30]. Such as the fiber-reinforced composites [31,32], metallic matrix composites and so on.…”
