【 摘 要 】

In this paper I have build some composite sandwich bars. For these bars I have determined thedynamic response by recording their free vibrations. These bars have the core made of polypropylenehoneycomb with upper and lower layers reinforced with steel wire mesh. For these bars I have determined thethe eigenfrequency of the first eigenmode in this way: the bar was embedded at one end and free at the otherwhere there was placed an accelerometer at 10 mm distance from the edge and I applied an initial force at thefree end. I have determined the eigenfrequency because I will use its values for the loss factor and dynamicYoung modulus determination.
