IPC: F16F15/02
Filed: 1993-09-28
Abstract: PURPOSE:To provide a vibration damping material which facilitates processing and has excellent damping ability by a method wherein capsule powder prepared by adhering carbon powder to the periphery of viscoelastic resin and a carbon powder lump are evenly disposed in a PB base material. CONSTITUTION:A sintered substance is brought into a state that it is approximately evenly dotted with polyethylene being viscoelastic resin and a carbon powder lump in a base material formed of lead and carbon powder is coagulated around the viscoeleastic resin in a manner to surround the resin with the carbon powder and present in a capsule powdery material state. The viscoelastic resin evenly dispersed in a PB base material in this composition is caused to deform vibration transmitted to the Pb base material for absorption. Further, friction occurs at a grain boundary between a carbon powder lump wherein a carbon powder lump in a non-sintered state and a carbon powder lump evenly dispersed in the Pb base material by incoming vibration through plastic flow operation. By converting it into heat energy, vibration is effectively damped.
