Structural damping of carbon fiber reinforced laminate composite is experimentally determined using a
cantilever beam test with an impulse excitation. Continuous carbon fiber reinforced laminates with different lamia orientation
were fabricated from MT300/603 and MT300/603A to investigate the effect of matrix properties and fiber orientation
on the damping of composite. The results show that the MT300/603A composite has a higher loss factor than
MT300/603. Fiber orientation has an important effect on the modal frequency and modal damping and the effect is
characteristic as changing structural flexibility. The 0° material exhibits a lighter damping loss factor than the other fiber
orientation.
