TOUGHENING OF EPOXIES VIA CRAZE-LIKE DAMAGE Academic Article

abstract

• The fracture behavior of a coreshell rubber (CSR) modified epoxy is investigated using both fracture mechanics and microscopy tools. The CSRmodified epoxy is found to be toughened via numerous linearray cavitations of the CSR particles, followed by plastic flow of the epoxy matrix. The toughening effect via the above crazelike damage process is found to be as effective as that of the wellknown widespread rubber cavitation/matrix shear yielding mechanisms. The conditions for triggering the crazelike damage appear to be both stress state and rubber concentration dependent. The type of rubber tougheners utilized also plays a critical role in triggering this rather unusual crazelike damage in epoxy systems. 1993 John Wiley & Sons, Inc.
