CORRELATION BETWEEN THE DAMPING FACTOR PER UNIT MASS AND THE FREE LENGTH FOR COMPOSITE SANDWICH BARS. EXPERIMENTAL INVESTIGATIONS
In this paper we have build some composite sandwich bars in this way: the core is made with polypropylene honeycomb (its thickness is 10, 15 and 20 mm) reinforced with 1 layer of carbon fiber (on the sample upper and lower sides). For these samples we have determined, by experimental means, the da...

| Summary: | In this paper we have build some composite sandwich bars in this way: the core is made with
polypropylene honeycomb (its thickness is 10, 15 and 20 mm) reinforced with 1 layer of carbon fiber (on the
sample upper and lower sides). For these samples we have determined, by experimental means, the damping
factor per unit mass and per unit length. Then, by using the regression analysis, we have established
correlations between the damping factor per unit mass and the bars free length. In order to obtain these
correlations, we have considered the next free lengths of the bars: 200, 230, 260, 290, 320, 350. |
