Abstract: Abstract Carboxyl‐terminated butadiene‐acrylonitrile‐rubber decreases modulus and yield stress of the studied epoxy but increases fracture toughness. The addition of glass bead compensates for the loss in modulus but has little effect on yield stress. However, it significantly contributes to the fracture toughness by providing additional mechanisms for toughening of both the unmodified and rubber‐modified epoxy. For the toughened epoxies studied, fracture surfaces gave only limited information on fracture mec…
