Abstract: PURPOSE:To obtain damping body having superior variation controlling efficiency against vibrating motions of a wide temperature range and a wide frequency range, by respectively setting the glass transition temperature, loss factor and Young's modulus of a first and a second vibration controlling bodies to be provided with an objective body within a specific range. CONSTITUTION:A composite of vibration controlling bodies of this invention is formed by laminating a first and a second vibration controlling body layers 2, 3 on the surface of an objective body 1 to be vibration-controlled. When the respective glass transition temperature, internal loss factor at the glass transition temperature and Young's modulus at 20 deg.C of the first and second bodies 2 and 3 are represented by Tg1, Tg2, tandelta1, tandelta2, and E1, E2, they are so set as to hold (Tg1+10)<Tg2[ deg.C], 5E1<E2[Pa], and tandelta1>=0.5, tandelta2>=0.5. Two materials having the glass transition temperature different by 10 deg.C or more from each other are used for the first and second bodies 2, 3 which are coated over the body 1, so that a vibration controlling efficiency is effected in a wide temperature range. Moreover, the selected materials of the first and second bodies 2, 3 have the loss factor not less than 0.5, and therefore a high vibration controlling efficiency can be achieved. Since the first vibration controlling body 2 is covered with the second body 3 of a larger Young's modulus, a high vibration controlling efficiency against vibrations of a wide frequency range can be obtained.
