New routes to improve toughness of rubber-modified epoxies
- Lehigh Univ., Bethlehem, PA (United States)
Significant progress has been made in modeling the toughening mechanisms in rubber-modified epoxies due to the efforts of many researchers. The result of these efforts has led to an increased awareness of the roles of rubber particle bridging, rubber particle cavitation, matrix dilation, and matrix shear banding on the enhancement of fracture toughness. However, there are still many questions regarding rubber-toughening which remain unanswered. This talk will focus on the importance and the roles of the interphase region between the epoxy matrix and the rubber particle and of the overall particle morphology on the toughness enhancement in rubber-modified epoxies. It will be demonstrated that additional toughness enhancement may be achieved by means not included in any of the toughening models proposed to date. Methods to incorporate these effects into existing toughening models will be discussed.
