【発明の名称】多層構造の外被を有するハニカム体
Document Type and Number:
Japanese Patent JP2003513190
Kind Code:
A
Abstract:
A honeycomb body, in particular a catalyst carrier body, includes a carrier matrix shell for a carrier matrix formed of partially structured, layered and/or wound or folded metal sheets. The carrier matrix has a plurality of passages which are fluid-permeable and extend substantially parallel to a central longitudinal axis. The carrier matrix shell has at least two individual, smooth layers, preferably with substantially the same thickness, disposed concentrically relative to one another and at least two of the layers are adjacent one another. In addition to an improved ability to compensate for expansion of a thermal origin, the honeycomb body has vibration damping and sound-proofing qualities, resulting from the multi-layer structure of the carrier matrix shell.
