A wall/roof panel includes (a) a façade that has (i) an outer surface that defines a front surface of the panel and (ii) a rear surface and (b) a structural element connected to and supporting the façade.

Disclosed herein is a sliding member having an alloy overlay layer that comes into sliding contact with a counterpart member thereof and has improved fatigue resistance. The sliding member comprises a base material layer and an alloy overlay layer formed on the base material layer, in which the alloy overlay layer has a soft metal phase made of tin and precipitated in a metallic matrix phase made of aluminum, and when an average aspect ratio of the soft metal phase is defined as A, and its standard deviation is defined as Aσ, A+Aσ is 3.0 or less. In this case, the soft metal phase has a shape close to a sphere without elongating in a certain direction.

A method of manufacturing an extruded material of carbon nanotube reinforced aluminum matrix composite having improved corrosion resistance, and the extruded material manufactured thereby are proposed. The method may include manufacturing an extruded material comprising an aluminum-carbon nanotube composite material and forming a hard oxide film on the surface of the extruded material by anodizing the extruded material in a mixed solution of sulfuric acid and oxalic acid. The method can form a hard oxide film with excellent corrosion resistance, abrasion resistance, and insulation properties on the surface of a composite material (an extruded material of carbon nanotube reinforced aluminum matrix composite material), which is known to be difficult to conduct hard anodizing due to the difference in corrosion characteristics between materials and, accordingly, the usability of the composite material can be significantly improved.
