RALUCA VOICU STRUCTURAL CHARACTERIZATION AND MECHANICAL BEHAVIOUR OF CARBON FIBER/EPOXY COMPOSITE FOR AERONAUTICAL FIELD In the present study EP142-C510-50 woven carbon fiber composite was investigated from structural/mechanical point of view aiming manufacturing parts for aeronautical industry. The composites were obtained by hand lay-up process. Prior to mechanical tests, the cure reaction results of composite resins specimens were analyzed by using DSC technique. The EP142 epoxy matrix was cured/polymerized at 160°C. After molding, the laminates were cut into specimens for 3 points flexure, tensile and fatigue tests. The mechanical tested samples observed by scanning electron microscopy revealed their fractured and microstructure aspects. A nondestructive US method allowing elastic constant determination on a composite plate was proposed during this study.
