摘要：

In the present work the impact behaviour at high speed of rubber-modified epoxy resins has been investigated. Impact-tension measurements have been performed to evaluate the toughness of different systems. A detailed post-failure observation of the fracture surfaces has been made through scanning electron microscopy (SEM). A combination of a solid fluorinated rubber with the generally used carboxy-terminated butadiene-acrylonitrile rubber (CTBN) was found to be very effective. A correlation was tempted between the observed fracture behaviour and the bulk morphology, examined by transmission electron microscopy (TEM).
