  • Publication number: 20130287877
    Abstract: A resin transfer molding (RTM) molding device is designed to mold a fiber-reinforced plastic (FRP) molded body by injecting a resin composition into a mold and by impregnating the molded body therewith. The resin composition is a chain curing polymer (CCP). A CCP accommodating layer is disposed adjacent to an outer side of the molded body. The layer contains the CCP. The layer is provided with a Vf limit value, the value defined by the curing characteristics of the CCP and the characteristics of dissipation of heat from the CCP to the exterior. An element for separating the molded body is disposed between the body and the layer.

  • Patent number: 8556240
    Abstract: A fluid-filled vibration damping device wherein a partition member is formed by fitting an inner orifice member inside an outer orifice member with the members relatively displaceable. An orifice-defining window is provided on either one of an inside peripheral face of the outer orifice member and an outside peripheral face of the inner orifice member. An orifice passage is defined utilizing a zone being produced through partial covering of the orifice-defining window by the other of the outer orifice member and the inner orifice member. The covered zone of the orifice-defining window changes through relative displacement of the inner orifice member and the outer orifice member, so that a passage length along the orifice passage changes in association with change of the covered zone of the orifice-defining window.
