The damp- Besides, carbon fiber reinforced composites generally have lower damping properties dur to their high stiffness, resulting in that the tiny cracks in many engineering structures fabricated by carbon fiber reinforced composites, including military equipment, automotive and aircraft parts, etc., will gradually propagate due to the fatigue loading In this study, the passive damping of carbon-fiber reinforced plastic (CFRP) cantilever beams is examined using (1) interleaving of viscoelastic thermoplastic films, (2) piezoelectric polymer (PVDF) film interlayers and (3) surface-bonded piezoelectric ceramics. Introducing polyethylene-based film interlayers between composite plies resulted in a significant increase in the vibration loss Polymer matrix composites reinforced by carbon nanofibers (CNFs) are rapidly gaining popularity in vibration damping applications. The large specific area (1000 m 2 /g) and aspect ratio (> 1000) of CNFs, which promote significant interfacial friction between carbon nanofibers and the polymer matrix, causes much higher energy dissipation in the polymer matrix.
