CRAZE-LIKE DAMAGE IN A CORE-SHELL RUBBER-MODIFIED EPOXY Conference Paper

abstract

• Failure mechanisms of a rubber-modified low crosslink density epoxy system were investigated using various microscopy techniques. It was found that the crack tip damage zone of the rubber-modified epoxy appeared to consist of multiple craze-like damage. The craze-like damage was further analyzed and actually found to be a collection of line arrays of cavitated rubber particles. The matrix material around the cavitated particles appeared to have plastically deformed, while the material outside of the array was undeformed. The structure and physical nature of this highly localized dilatational process are substantially different from those of the commonly known craze. The failure mechanisms of this rubber-modified epoxy system are discussed. The sequence of events leading to the formation of these craze-like arrays is also addressed.
