The article reviews low velocity impacts in aircraft structures in terms of resin toughness, laminate thickness, specimen size and impactor mass, and post-impact fatigue. It explains the tension strength analysis, such as linear elastic fracture mechanics and R-curve methods...

... epoxy-matrix system suited to a service temperature up to 177 °C (350 °F) would have TGDDM as epoxy A, diaminodiphenylsulfone as the curing agent, and a salt of BF 3 as the catalyst. Elastomer modifiers or flexible resins would be added as needed to improve toughness. For both of these examples, high...

... copolymers were patented in Switzerland in 1975, but the significance of the invention, that is, their toughness, was not recognized before toughness became an issue to the aerospace industry. Experience has taught that a useful BMI-resin comprises both a BMI part and a comonomer part. Bismaleimide...

... be homogeneous and single phase before impregnation, or the particles may become filtered by the fibers. This limits the use of some standard prepreg curing agents and modifiers, because many are in particle form ( Fig. 8 ). Also, because the resin is not preimpregnated, many conventional toughness modifiers...

This structure results in a thermoset resin that has a lower cross-link density. These resins display greater toughness properties...
