Improving the fracture toughness and the strength of epoxy using nanomaterials – a review of the current status

摘要: The incorporation of nanomaterials in the polymer matrix is considered to be a highly effective technique improve mechanical properties resins. In this paper effects addition different nanoparticles such as single-walled CNT (SWCNT), double-walled (DWCNT), multi-walled (MWCNT), graphene, nanoclay and nanosilica on fracture toughness, strength stiffness epoxy have been reviewed. Young's modulus (E), ultimate tensile (UTS), mode I (GIC) II (GIIC) toughness various nanocomposites at nanoparticle loadings are compared. review shows that, depending type nanoparticles, integration has substantial effect stiffness. critical factors maintaining homogeneous dispersion good adhesion between highlighted. surface functionalization, its relevancy toughening mechanism also scrutinized discussed. A large variety data comprised nanomaterial toughened composites reported date thus compiled facilitate evolution emerging field, results presented maps showing loading strength.
