  • Patent number: 11945147
    Abstract: A vehicle interior and exterior member comprises a fiber molded body and a synthetic resin member fixed to a surface of the fiber molded body. The fiber molded body has a fiber layer including thermoplastic synthetic resin as a base material layer. The base material layer has fiber layer surfaces on its both surfaces or, the base material layer has another fiber layer including the other type of thermoplastic synthetic resin on one of the fiber layer surface to form a fiber laminated body. The fiber molded body is formed by molding the fiber laminated body into a three-dimensional face shape. The synthetic resin member has a fixed portion which is fixed to the fiber molded body by solidifying it in a state that molten synthetic resin has seeped into the fiber layer of the fiber laminated body.

  • Publication number: 20230303013
    Abstract: A vehicle interior or exterior member includes a base material layer laminated with a sound-absorbing layer. The base material layer is a fiber molded body containing a thermoplastic synthetic resin. The sound-absorbing layer includes a fiber web and a cover layer. The cover layer is a nonwoven fabric containing a thermoplastic synthetic fibers and covers the fiber web. The vehicle interior or exterior member includes a bonding portion, a sound-absorbing portion, and a crimped portion. The bonding portion includes the thermoplastic synthetic fibers on the surface of the sound-absorbing layer in contact with the thermoplastic synthetic resin in the base material layer thermally being bonded to each other. At a position separated from the base material layer, the sound-absorbing portion remains in a fiber web state.

  • Publication number: 20230219505
    Abstract: A sound-absorbing material attached to a vehicle exterior member which comprises an intermediate layer having a fiber web of entangled thermoplastic synthetic fibers, and a skin layer having a nonwoven fabric containing thermoplastic synthetic fibers, the layers being laminated with each other. A peripheral edge portion is heat-compressed in a state where the intermediate layer and the skin layer are layered. A crimped portion is heat-compressed in the thickness direction. A plurality of the crimped portions are provided on at least a part of the surface of the intermediate layer laminated with the skin layer and positioned within the peripheral edge portion. A sound-absorbing portion is a portion in which the intermediate layer and the skin layer are laminated in a state where the fiber web is compressed thinner than its natural thickness by the crimped portions.

  • Patent number: 10889331
    Abstract: A hood silencer includes a back skin layer, a thin film layer, a first shape-retaining layer, a sound-absorbing layer, a second shape-retaining layer, an aeration-suppressing layer, and a front skin layer. The aeration-suppressing layer suppresses oozing of a binder resin out of the surface of the front skin layer from the second shape-retaining layer during the heat forming of the second shape-retaining layer.
