There are two main paths for energy dissipation at the fiber–matrix interface: relative friction and crack propagation. Both can greatly contribute to improved damping. Se hela listan på The damping of fiber reinforced composite materials has been studied extensively [18-20]. All of the published results for continuous fiber reinforced composites show that when strain levels are low the damping characteristics do not depend on strain amplitude but are dependent on fiber orientation, temperature, moisture Synthetic Fiber Suspension Ropes on P&H 4100 Rope Shovel Dampen Shock Loads 50% as a result of Boom Jacking Reduce Vibration and Machine Fatigue Reduce Downt As with other properties, damping properties in unidirectionally reinforced c/ep composites are anisotropic, with the longitudinal (fiber) direction dominated by relatively stiff, lightly-damped fibers and the transverse and shear directions being dominated by the relatively compliant, viscoelastic matrix [2,3]. damping properties of carbon-fiber reinforced interleaved epoxy composites. Several types of commercial-based thermoplastic-elastomer films, such as polyurethane elastomers, polyethylene-based ionomers and polyamide elastomers were compared as the interleaving materials for composite laminates.

Fiber-reinforced composites are induced by different processes such as the viscoelastic behavior of matrix and the damping at the fiber-matrix interface. At the laminate level, damping depends on the constituent layers properties as well as their orientations, interlaminar effects, stacking sequence, and so on. Increased damping has been demonstrated for graphite/epoxy composite material made using bromine-intercalatefd graphite fiber. A resonant forced-vibration test method was used to measure the damping of unidirectional graphite/epoxy flexural specimens, at frequencies of about 100 hz, and at temperatures ranging from -120 to +30 degrees C. Specimens made from pristine P-100 as well as treated P Fiber contribution to modal damping was found to be significant in vibration modes involving longitudinal deformation of fibers. For a [0] 8 P100/3501-6-square cantilevered laminate, in vacuum and at room temperature (20° C), the predicted first mode damping showed an increase of 77 % by including fiber damping.
