TY - JOUR T1 - The Effect of Fiber Direction on the Adhesion Strength and Energy Release Rate in Epoxy Composite using Defragment Test AU - Hasan, Hisham Mohammed Ali AU - Ismaeel, Zaineb Maeh JO - Research Journal of Applied Sciences VL - 13 IS - 5 SP - 328 EP - 331 PY - 2018 DA - 2001/08/19 SN - 1815-932x DO - rjasci.2018.328.331 UR - https://makhillpublications.co/view-article.php?doi=rjasci.2018.328.331 KW - Polymers composites KW -fiber reinforced KW -adhesion strength KW -energy release rate KW -defragment test AB - In this study, the adhesion strength and the energy release rate measured using defragment test for non-woven three kinds of unidirectional laminate composite specimens reinforced by carbon, Kevlar and glass fibers 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 rate of laminate composite specimen is at 0° direction for each kind of specimens while the high value of strength and the energy release rate of laminate composite for all kinds of specimens found in epoxy reinforcement Kevlar.
