Experimental Investigation on Modal Response of Woven Fabric Carbon Composite Plate Reinforced with Particles of Micro Rubber Blended Epoxy Matrix under Free Vibration Condition

Abstract:

Vibration damping is proving important for improved vibration control and dynamic stability in advanced engineering systems like aerospace systems, automobiles and in ship building industry. In the present investigation, vibration characteristics of woven fabric carbon composite plate reinforced with micro rubber particle blended into epoxy matrix is studied for enhancing the vibration damping performance. Test Specimens are fabricated in the form of hand layup method. CTBN rubber particle size of 5μm is selected and added to the epoxy matrix for fabricating carbon/epoxy composite plates. Rubber particles of 3% & 15 % by weight were considered as blended percentage in epoxy matrix and compared with 0% addition of rubber particles for understanding and analyzing the vibration characteristics and its difference in damping performance. Vibration damping and modal responses of various kinds of prepared plates were studied and compared. Among tested samples, carbon/epoxy composite plate with 15 wt % micro rubber particle by weight showed very good damping performance.
