Acoustic and thermal insulation, in a board structure, has a number of layers with woven materials of metal warp and weft filaments bonded together at their contact points leaving open pores

摘要

The acoustic and thermal insulation is a board, where at least one layer (3,9,11,12,13) is a woven metal material (4,10,14,15,16) with warp and weft filaments. The warps and wefts are bonded together at their contact points by sintering, leaving open pores, which can be filled at least partially by rubber, ceramics, etc.. The woven metal layers are placed over each other with different orientations.
