摘要: We propose a new 1–3 piezoelectric composite comprised of armchair single-walled carbon nanotubes imbedded in piezoceramic matrix which we call NRPEC (nanotube reinforced composite). Values effective and elastic moduli the determined through micromechanical analysis are found to be significantly higher than those fibers an epoxy matrix. The performance NPREC as constraining layer active constrained damping (ACLD) treatment laminated beam has been studied by finite element method. Both in-plane out-of-plane actuations ACLD have considered, its length optimized implementing controllability criterion. computed measure frequency response reveal that proposed performs better piezoelectric/epoxy layer.
