Provided is a method of manufacturing a stabilizer bar with a rubber bush including manufacturing a rubber bush without an intermediate plate by subjecting a rubber composition containing butadiene rubber and natural rubber as a polymer to vulcanization molding; applying a thermosetting adhesive onto at least one of an inner peripheral surface of the rubber bush and an outer peripheral surface of the stabilizer bar, to thereby form a thermosetting adhesive layer; inserting and fitting the stabilizer bar into the rubber bush; holding the rubber bush with a fixing jig such that the rubber bush is compressed at a rate of 0% to 5%, at 25° C., in a direction of the stabilizer bar fitted into the rubber bush; and heating the rubber bush in the state to cure the thermosetting adhesive, to thereby bond and fix the rubber bush onto the stabilizer bar.

An apparatus for laminating a fiber tow is provided. The apparatus includes a supply unit that supplies a fiber tow impregnated with resin. A laminating unit is configured to move along a surface of a lamination object and has a shock-absorption element to laminate a fiber tow supplied from the supply unit on a surface of the lamination object.

The present invention discloses a high-sound-absorption composite material for a traffic sound barrier. The surface of a porous sound-absorption material layer is clad with a cladding layer in a sealing way, and the clad parts and joints are in sealed connection. The cladding layer is an expanded polytetrafluoroethylene microporous membrane or a modified membrane of the expanded polytetrafluoroethylene microporous membrane. A preparation method is disclosed, comprising the following steps of cutting the porous sound-absorption material; covering the surface of the porous sound-absorption material with the expanded polytetrafluoroethylene microporous membrane or the modified membrane of the expanded polytetrafluoroethylene microporous membrane; performing sealed connection on the clad parts and joints. By the above approach, the present invention is able to greatly reduce noise, has a soundproof function and a better sound-absorption function, has a prolonged service life, and features environmental protection, flame retardancy, damp-proofing and high plasticity.

Disclosed is a method of manufacturing a final piece including several materials, the final piece being produced at least according to the steps of: inserting an elastomer (5) in at least one insertion cavity (6) of an initial piece (2) so that the elastomer (5) is in contact and fixed with the initial piece (2); then cutting the initial piece (2) in at least two distinct parts (3, 4), so that the at least two distinct parts (3, 4) are fixed together but not in contact with each other, the at least two distinct parts (3, 4) being connected together by the elastomer (5). This may be applied to manufacturing a final piece including several parts, of various natures, connected together.

A method of preparing a cured air spring bellows includes preparing a vulcanizable composition including a eutectic composition by mixing a vulcanizable elastomer, a sulfur-based curative, zinc oxide, and a eutectic composition; preparing a green member using the vulcanizable composition; and curing the green member to form the air spring bellows.

A formation method for liquid rubber composite nodes with middle damping holes is provided. The formation method includes adding a middle spacer sleeve between an outer sleeve and a mandrel, bonding the middle spacer sleeve and the mandrel together through rubber vulcanization, and assembling the integrated middle spacer sleeve and the mandrel into the outer sleeve; forming damping through holes which penetrate through the mandrel on the mandrel; hollowing the middle spacer sleeve to form a plurality of spaces; after vulcanization, forming a plurality of interdependent liquid cavities by using rubber and the plurality of spaces; and arranging liquid in the plurality of liquid cavities and communicating the plurality of liquid cavities through the damping through holes.

In one example, an electronic device housing may include a metal substrate defining an opening and a shock absorber in-mold molded with the metal substrate. Further, shock absorber may include a supporting portion formed on a surface of the metal substrate and a protruding portion that extends from the supporting portion through the opening. Further, the electronic device housing may include a metal layer disposed on the supporting portion.

During the transition from the opening to the closing movement of a glove compartment door, or vice versa, undesirable noises (“clicking”/“popping”) can be reduced by providing regions of a housing surrounding a rotation damper with a contact region made of a material having a lower modulus of elasticity than the material of the remainder of the housing.

A stabilizer adhesive bearing for a vehicle stabilizer may comprise an annular sleeve having a resilient inner contour for coaxial arrangement on the vehicle stabilizer. The resilient inner contour of the annular sleeve may comprise on a side facing the vehicle stabilizer a three-dimensionally structured surface with an adhesive receiving volume. The three-dimensionally structured surface has a maximum roughness depth (R.sub.max) greater than 45 μm and a core roughness depth (R.sub.K) of at least 65% relative to the maximum roughness depth (R.sub.max) of the three-dimensionally structured surface. The maximum roughness depth (R.sub.max) is a total of the reduced tip height (R.sub.pk), the core roughness depth (R.sub.K), and the reduced groove depth (R.sub.vk). Further, the reduced tip height (R.sub.pk), the reduced groove depth (R.sub.vk), and the core roughness depth (R.sub.K) may be determined in accordance with EN ISO 13565-2: December 1997.

Impact protection plate for a vehicle comprising at least an impact layer with an outer surface for receiving the impact comprising at least one fiber reinforced thermoplastic polymer layer, and whereby the impact protection plate further comprises a spacer layer comprising at least one thermoplastic polymer layer, formed in a 3-dimensional shape with one or more protrusions, and whereby the impact layer and spacer layer are at least over part of their surface materially connected to each other forming one or more cavities between the impact layer and the spacer layer.
