Abstract
In the present work, the modal parameters such as fundamental natural frequency, mode shapes and damping are estimated for honeycomb sandwich composites by varying cell size and its effect on parameters have been studied. Experimental Modal tests were conducted on hexagonal cell honeycombs of sizes 6 and 12 mm maintaining the facing thickness constant at around 1 mm with three different boundary conditions viz C-F-F-F, C-F-C-F and C-C-C-C. The traditional “strike method” has been used to measure the vibration properties. The modal characteristics of the specimens have been obtained by studying its impulse response. Each specimen has been subjected to impulses through a hard tipped hammer which is provided with a force transducer and the response has been measured through the accelerometer.
