Laminaari

Laminaari is a Finnish noun that denotes a thin, flat layer or plate and is used in several scientific and engineering contexts. In mathematics and physics, a laminaari refers to a flat, two‑dimensional body of negligible thickness used to model distributions of mass, charge, or other properties over a plane region. Such a laminaari is analyzed through quantities like area, centroid, and moments of inertia, typically computed by integrating over the plane.

In materials science and manufacturing, laminaari commonly means a laminate—a material formed by stacking and bonding multiple layers. Each layer is usually a sheet of material, such as wood veneer, plastic film, metal foil, or a composite ply. The arrangement and properties of the layers determine the mechanical, thermal, and electrical behavior of the final product, with common examples including plywood, laminated glass, and printed circuit boards.

The term is also used for thin, layered coatings or veneers in everyday language and technical contexts to describe multilayer structures. The word laminaari derives from Latin lamina, meaning a thin plate or layer, with body of usage spanning mathematics, physics, and engineering to denote either a flat idealized region or a real multilayer material.
