A composite material steel sheet comprises: at least one steel sheet, and a resin-impregnated paper composite layer, wherein the resin-impregnated paper composite layer may comprise stacked sheets of paper, and impregnated resin provide adhesion between the sheets of paper in contact with each other.

The invention relates to a multilayer structure comprising at least three layers and to a method for the production and use thereof.

The present invention relates to a surface-treated metal sheet for polyolefin resin bonding having a metal substrate and an adhesive layer laminated on at least one surface of the metal substrate with a chemical conversion coating film interposed between the metal substrate and the adhesive layer. This surface-treated metal sheet for polyolefin resin bonding is characterized in that a coating liquid for forming the chemical conversion coating film contains an acid-modified polyolefin resin, a colloidal silica, and a silane coupling agent; a coating amount of the chemical conversion coating film is 0.05 to 3 g/m.sup.2 in terms of dry mass; the adhesive layer contains an acid-modified polyolefin resin; and the adhesive layer has a thickness of 5 to 100 m.

Provided is a nonwoven fabric and a laminated nonwoven fabric suitable as the skin material of a composite sound-absorbing material. The nonwoven fabric and laminated nonwoven fabric are easily formable, thin, and lightweight and excel in form stability, and can nevertheless be controlled within a given range of aeration after being formed into shape. A nonwoven fabric having a laminate structure in which at least one ultra-fine fiber layer (M) having an average fiber diameter of 0.3 to 7 m (inclusive) and a basis weight of 1 g/m.sup.2 to 40 g/m.sup.2 (inclusive) and at least one continuous filament layer (S) having an average fiber diameter of 10 to 30 m (inclusive) are integrated together by partial thermocompression bonding.

A glass article (100) includes a core layer (102) formed from a core glass composition with a core coefficient of thermal expansion (CTE) and first (104) and second (106) cladding layers fused to first and second major surfaces of the core layer (102) and formed from a clad glass composition comprising a clad CTE. An aperture (120) extends through each of the core layer (102), the first cladding layer (104), and the second cladding layer (106). The clad CTE is less than the core CTE such that each of the first (104) and second (106) cladding layers is under a compressive stress and the core layer (102) is under a tensile stress. A flexural strength of the glass article (100) can be at least about 75 MPa. A peak load sustainable by the glass article (100) in a modified ring-on-ring test can be at most 96.5% less than a peak load sustainable by a reference glass article in the modified ring-on-ring test.
