Smart Control of Clamped-Clamped Sandwich Plates Composed of Fuzzy Fiber Reinforced Composite Facings
Abstract
This paper addresses the analysis of active constrained layer damping (ACLD) of smart laminated composite sandwich plates. The top and bottom layers of the sandwich plate are composed of fuzzy fiber reinforced composite (FFRC) facings containing straight carbon nanotubes CNTs. These CNTs are radially grown on the surface of the fibers which are then embedded in the matrix. The constrained viscoelastic layer is sandwiched between the substrate sandwich plate and the constraining 1-3 piezoelectric composite (PZCs) layer. The core of the sandwich plate is a HEREX honeycomb and honeycomb with foam fill material. Layer wise displacement fields have been derived considering the continuity between the individual layers of the sandwich plate using the first order shear deformation theory (FSDT) and a three dimensional finite element model has been developed by user generated MATLAB coding. The effect of radially grown CNTs of FFRC of the sandwich plate on the frequency responses of clamped-clamped boundary conditions has been studied. Emphasis has also been placed on investigating the effect of the variation of piezoelectric fiber orientation angle on the control authority of ACLD treatment has been thoroughly investigated
