dc.description.abstract | The toughening mechanisms of elastomer-modified epoxies are examined by scanning electron microscopy, transmission electron microscopy, and optical microscopy, DGEBA epoxies toughened by various levels of several types of carboxyl terminated copolymers of butadiene-acrylonitrile (CTBN) liquid rubber are studied. The materials are deformed in uniaxial tension and in three-point bending with an edge notch. Scanning electron microscopy of fracture surfaces indicate cavitation of the rubber particles to be a major deformation mechanism. Particle-particle interaction is also found. Optical microscopy of thin sections perpendicular to the fracture surface shows that the cavitated particles generate shear bands. The toughening effect is hypothesized to be due to cavitation, which relieves the triaxial tension at the crack tip, and shear band formation, which creates a large plastic zone. | en_US |
