A hybrid-layered apparatus for a bulletproof structure includes a viscous absorber layer, a first elastic layer, a viscous-elastic foundation layer, and a second elastic layer, orderly arranged in a lamination manner The viscous absorber layer contains a semi-liquid viscous material. The first elastic layer, laminated fixedly to the viscous absorber layer, has a first predetermined toughness. The viscous-elastic foundation layer, laminated fixedly to the first elastic layer by opposing the viscous absorber layer, has predetermined elasticity and compressibility. The second elastic layer, laminated fixedly to the viscous-elastic foundation layer by opposing the first elastic layer, has a second predetermined toughness. In addition, the first predetermined toughness is higher than the second predetermined toughness.

A composite storage tank may include a wall structure including at least three regions including an inner region, an outer region, and at least one permeation barrier. Another region may be optionally incorporated for venting potential permeation of fluids. The at least one permeation barrier and/or the venting layer may be strategically positioned between the inner region and the outer region to reduce or at least partially prevent fluid permeation of the inner region or the outer region. A vehicle may include such a composite storage tank. Methods of forming a composite fluid storage tank may include forming an inner composite region, applying a permeation barrier to an outer surface of the inner composite region, forming an outer composite region, and curing the inner composite region and the outer composite region with the permeation barrier to form the composite fluid storage tank.

Provided are vacuum-insulated articles that comprise an evacuated space disposed between first and second walls and a reflective material disposed within the evacuated space. Also provided are methods of fabricating such articles.

A part includes a base material, a colored layer on the base material, and a surface layer on the colored layer, wherein the colored layer contains Zr, and optionally, C and/or N, a ratio (H.sub.Zr .sub.oxide/H.sub.Zr) of a peak height derived from Zr oxide (H.sub.Zr oxide) to a peak height of Zr (H.sub.Zr) at an interface of the colored layer on the side of the surface layer is more than 0 and less than 4.5, the interface is a point where Zr is detected by sputtering the part from the side of the surface layer with an XPS depth direction analysis, and the ratio (H.sub.Zr oxide/H.sub.Zr) at a point where Ar sputtering is performed for 5 minutes from the interface of the colored layer on the side of the surface layer with the XPS depth direction analysis is 0 to less than 3. The surface layer is water-repellent and exhibits a sputtering time of 5 minutes or less
