Double cantilever beam, end-notched flexure and single leg bending tests were used to determine the effects of temperature and moisture on the toughness of a thermoplastic particulate-toughened carbon/epoxy composite. Tests were performed on both dry and moisture-saturated specimens at temperatures of -43 degrees C, 21 degrees C and 98 degrees C, and on dry specimens only at 125 degrees C. In-situ observations and post-test scanning electron microscopy showed increasing matrix ductility with increasing temperature and moisture content. This correlated to an increase in the mode I and a decrease in the mode II toughness. The mixed-mode toughness data and fracture surface morphologies displayed a blend of the mode I and mode II behaviors. (C) 2008 Elsevier Ltd. All rights reserved.
