Influence of Multiwalled Carbon Nanotubes in the Structural Performance of the Curved Composite Beam

In this paper, Experimental investigation on the free vibration response bheavior of multi walled carbon nanotubes (MWCNT) reinforced curved composite beams have been accomplished to evaluate the structural integrity. To obtain the uniform distribution of MWCNTs in the matrix (epoxy), the ultra-sonication technique is carried out and the curved composite beams are fabricated with the incorporation of MWCNT with the curvature radius of 0.8 m then the free vibration analysis is performed at different boundary conditions. The structural performances of the curved composite beams are explored in the relation of modal natural frequencies and damping ratio. The effective structural integrity and vibration responses are achieved with respect to the enhancement of MWCNT in the curved composite structure.
