A tire for a heavy construction-type vehicle includes a tread, a radial carcass reinforcement, and a crown reinforcement. The crown reinforcement includes a working reinforcement and a hoop reinforcement. The working reinforcement includes two working layers, each of which includes inelastic metallic reinforcers that are crossed from one layer to a next layer and that make an angle in a range of from 15 to 40 with respect to a circumferential direction. The hoop reinforcement, which is a ply that is wound circumferentially to form a radial stack of at least two hooping layers, includes circumferential elastic metallic reinforcers that make an angle equal to at most 2.5 with respect to the circumferential direction. The hoop reinforcement is radially positioned between the working layers, and the circumferential metallic reinforcers of the hoop reinforcement have a force at break equal to at least 800 daN.

The present invention has an object to provide a laminated molded body in which a thin fiber reinforced layer is laminated and having a favorable strength characteristic. The laminated molded body (1) includes a laminated portion (a laminated portion of SR.sub.1 on an upper side and SR.sub.1, for example) in which fiber reinforced layers SR.sub.1 to SR.sub.n, each having a thickness of 20 to 80 m in which a reinforcing fiber material is dispersed in a thermosetting resin material which serves as a matrix, are laminated, and a laminated portion in which a resin layer is laminated between the fiber reinforced layers (a laminated portion of SR.sub.2 on the upper side, TP.sub.1, and SR.sub.3, for example).

A structure includes a first substrate and a variable grain layer disposed on or formed into the first substrate. The variable grain layer includes a first grain portion having a first grain size and second grain portion having a second grain size. The first grain size is smaller than the second grain size.

To provide a multilayer structure having high gas barrier property and crack resistance as well as excellent fatigue resistance, an inner liner for a pneumatic tire using such a multilayer structure, and a pneumatic tire comprising the inner liner. According to the present invention, in a multilayer structure 1 including a barrier layer 2 and an elastomer layer 3, a proportion of a thickness of the elastomer layer 3 in the multilayer structure ((U1+U2+ . . . +Un)/T) is 60% or more.

The present invention is to provide a biaxially-stretched layer polyamide film which is excellent in bag breakage resistance, impact resistance and bending fatigue resistance, particularly in bending fatigue resistance under low-temperature environments, is excellent in an effect such as bag breakage prevention during transportation or storage of products when used as a packaging material for packaging foods or the like, can exhibit both high heat seal strength and good appearance even when being automatically filled with a liquid soup, a seasoning agent, or the like at a high speed, and further has improved volume reduction performance and environmental friendliness as compared with conventional polyamide films, and is thus suitable for various packaging applications, particularly for packaging bags for filling liquid materials such as soup and sauce. The biaxially-stretched layer polyamide film comprising: an A layer of a mixed polymer containing 97 to 70 wt. % of an aliphatic homopolyamide, 3 to 20 wt. % of an aliphatic copolyamide, and 0 to 10 wt. % of a thermoplastic elastomer, and a B layer of a mixed polymer containing 99.5 to 90 wt. % of an aliphatic homopolyamide and 0.5 to 10.0 wt. % of a thermoplastic elastomer, the B layer being layered on at least one surface of the A layer, and a film thickness of less than 9 m.

A pre-stressed structure and a method for forming a pre-stressed structure are provided. The pre-stressed structure comprises a panel including a first region pre-stressed into a condition of membrane tension, resulting in the panel having increased transverse stiffness. The pre-stressed structure may further comprise a second region pre-stressed into a condition of membrane compression. The panel may be a plate or a shell and may form part of an insulating glass unit, which in turn may form part of a curtainwall unit.

Disclosed is a laminate including a first metal sheet and an adhesive layer bonded to the first metal sheet, in which the following relationship applies: 1(E.sub.metal*t.sub.metal)/(E.sub.adh*t.sub.adh)15 (1), where E.sub.metal=tensile Young's modulus of the first metal sheet, t.sub.metal=thickness of the first metal sheet, E.sub.adh=tensile Young's modulus of the adhesive layer, and t=thickness of the adhesive layer. The adhesive layer may include reinforcing fibers. The laminate may be used for providing a fatigue resistant structure, such as an aerospace structure, and shows a high crack growth resistance, in particular near edges of the structure.

A coated high-temperature component including a cobalt coating that has a higher carbon content is provided. A layer composed of a cobalt-based alloy is applied which is known as or is similar to substrate material, to the region of the component which is subject to the wear, wherein the component preferably comprises a nickel-based alloy as substrate material, the carbon content of which is lower than that of the cobalt-based alloy. At the high operating temperatures, carbon diffuses from the coating into the base material; this is normally undesirable, but here leads to a higher carbide proportion in the substrate and therefore to a higher hardness and therefore to an increased wear resistance.
