    Abstract: Disclosed is a method and electromagnetic device for manufacturing an anisotropic magneto-rheological elastomer (MRE) with an improved magneto-rheological effect. The electromagnetic device includes upper and lower electromagnets, and a test piece located therebetween. The upper and lower electromagnets are configured to apply a magnetic field of variable strength, which may be controlled by current applied from a power controller, to the test piece in a desired direction or orientation. More specifically, the device is designed in such a manner that carbonyl iron powder (CIP) (magnetic-responsive particles) dispersed in a magneto-rheological elastomer using natural rubber as a matrix can be oriented in the application direction of the magnetic field. A MRE produced by the method and electromagnetic device of the invention prevents formation of bubbles within a test piece, thereby improving the arrangement/orientation of CIP with the matrix.

  • Patent number: 8415426
    Abstract: A tire is provided having a component comprised of a rubber composition containing at least one conjugated diene-based elastomer and a combination of rubber reinforcing fillers composed of rubber reinforcing carbon black, precipitated silica and granular functionalized mineral comprised of at least one of aluminum hydrate (ALOOH) and titanium dioxide. The granular mineral is functionalized by pretreatment with a coupling agent. The granular mineral fillers are pretreated with a coupling agent to promote a combination of rubber reinforcing effect for the mineral fillers and to promote a hydrophobation of the mineral fillers to promote their dispersability in the rubber composition.
