| Abstract: | New piezoelectric mechanical dampers have been fabricated by using composites of polymer (CPE) :piezoelec-tric(BaTiO_3) :carbon fiber(VGCF) . Mechanical vibration energy,Transmitted to piezoelectric particles, is converted into electric energy by piezoelectric effect, is converted into Joule's heat through the conduction paths between electroconduc-tive fiber in the polymeric matrix. This is a new damping mechanism. |
