abstract
The fracture behavior of core-shell rubber (CSR) toughened -zirconium phosphate (ZrP) epoxy nanocomposite is investigated. The combined use of ZrP and CSR can greatly improve both the modulus and fracture toughness of epoxy. The fracture mechanisms change from brittle fracture via ZrP delamination to matrix shear yield after addition of CSR. Approaches for producing toughened high performance polymer nanocomposites are discussed.
