Abstract: Described embodiments relate to a method of manufacturing a sound absorption material. The method comprises: forming a low density fibrous web to act as porous bulk absorber, the fibrous web containing a proportion of bi-components fibers, each bi-component fiber having a core material and a sheath material around the core material; applying a thin facing later to the low density fibrous web, wherein the facing layer is adhesively compatible with the sheath material; heating the fibrous web to a temperature sufficient to soften the sheath material of at least some of the bi-component fibers; and pressing the facing layer and fibrous web together under low pressure such that at least part of the facing layer contacts the softened sheath material of at least some of the bi-component fibers to form an adhesive bond between the facing layer and the fibrous web.

Abstract: An adhesive material and articles incorporating the same is disclosed. The adhesive material includes a liquid epoxy resin and rubber, a solid epoxy resin and rubber, one or more curing agents, and a filler.

Abstract: An insert comprising: a first carrier portion, the first carrier portion including: at least one attachment portion; a non attachment portion; and a portion of a channel, the channel being surrounded by the attachment portion and the non-attachment portion, and extending along all or a portion of the longitudinal axis of the first carrier portion; a second carrier portion, the second carrier portion including: at least one attachment portion; a non-attachment portion; and a portion of a channel, the channel being surrounding by the attachment portion and the non-attachment portion, and extending along all or a portion of the longitudinal axis of the second carrier portion; wherein the first carrier and the second carrier are attached via the respective at least one attachment portions forming a channel between the first carrier portion and the second carrier portion so that components, devices, fluids, or a combination thereof may pass through all or a portion of the insert.
