摘要：In this study, the adhesion strength and the energy release rate measured using defragment test fornon-woven three kinds of unidirectional laminate composite specimens reinforced by carbon, Kevlar and glassfibers with fiber volume fraction ratio 4.8%, the direction of fiber in angles: 0°, 45°, 90° with the loading direction,all samples post cured at temperature 25°C. From results, the high value of strength and the energy release rateof laminate composite specimen is at 0° direction for each kind of specimens while the high value of strengthand the energy release rate of laminate composite for all kinds of specimens found in epoxy reinforcementKevlar.
