Method of making woven acoustical panel

摘要: Acoustical panels are comprised of woven fabrics which have at least one face ply portion warp and fill yarns comprising non-fugitive fugitive material. The fabric is relatively densely to facilitate handling use thereof in fabrication the acoustical panel. substantial disintegration strands yarn completion process provides a selected porosity for controlled transmission sound waves into interior In preferred method making an panel, mixture After installation porous elements pockets formed insertion mandrels flutes within fabric, impregnated with resin, cured, removed. panel then heated temperature sufficient burn out without affecting provide desired waves.
