摘要：Provided is a vibration damping material, which includes a resin compositionobtained by dispersing titanium dioxide (Y) and a mica flake (Z) in a polyester resin (X)containing dicarboxylic acid constitutional units an diol constitutional units, in which: (1) inthe polyester resin (X), a ratio of a total of a number of the dicarboxylic acidconstitutional units (A) having an odd number of carbon atoms in a main chain and anumber of the diol constitutional units (B) having an odd number of carbon atoms in amain chain with respect to a total of a number of total dicarboxylic acid constitutionalunits (A) and a number of total diol constitutional units (B), i.e., [(A1+B1)/(A+B)] is in arange of 0.5 to 1; and (2) a mass ratio (X:Y:Z) of the polyester resin (X), the titaniumdioxide (Y), and the mica flake (Z) is in a range of 15 to 40:5 to 30:30 to 80. The vibrationdamping material is light, has a high vibration damping ability, and exhibits a highervibration damping ability in a particularly wide range of frequency. Because the vibrationdamping material does not require use of a carbon powder or the like, the material canalso be used in applications and parts that require various color tones, and has highversatility.
