Fatigue crack propagation in triblock copolymer toughened epoxy nanocomposites

This study systematically investigates the influence of a Polymethylmethacrylate‐block‐Polybutylacrylate‐block‐Polymethylmethacrylate (PMMA‐b‐PBuA‐b‐PMMA) triblock copolymer (BCP) on the flexural properties, the static fracture toughness and especially the resistance to fatigue crack propagation (FCP) of a cycloaliphatic amine cured bisphenol A based epoxy resin (EP). The results show that already small concentrations of BCP can significantly...
