Fracture behavior of core-shell rubber-modified crosslinkable epoxy thermoplastics
Fracture behavior of core-shell rubber-modified crosslinkable epoxy thermoplastics
- Colloid & Polymer Science, 272(4), p.456-466, 1994 .
The fracture behavior of a core-shell rubber (CSR)modified cross-linkable epoxy thermoplastic (CET)system, which exhibits high rigidity, highT g, and low crosslink density characteristics, is examined. The toughening mechanisms in this modified CET system are found to be cavitation of the CSR particles, followed by formation of extended shear banding around the advancing crack. With an addition of only 5 wt.
