Toughening of dicyanate matrix composites with particulate‐modified resin‐rich interlayers was investigated in this study. Specifically, the cure behavior, viscosity, and fracture toughness of the modified dicyanate systems were analyzed. Creation of a layered composite structure showed no improvement in Mode 1 interlaminar fracture toughness (GIc) , but greatly increased the Mode II interlaminar fracture toughness (GIIc). Furthermore, the concentration of modifier particles in the interlayer resin was found to directly affect the toughness improvement and fracture path.
