Lamelliert

Lamelliert, or lamellated, describes objects or structures that are composed of thin plate-like layers called lamellae. The term derives from the Latin lamella, meaning a small plate, and is used across disciplines to indicate a layered arrangement that can influence strength, flexibility, and function.

In biology, lamellae appear in several forms. Lamellar bone has a layered organization of mineralized collagen fibers, in contrast to woven bone. In chloroplasts, thylakoid membranes are arranged into grana and connecting stroma lamellae. Some sensory receptors, such as Pacinian corpuscles, are described as lamellated due to their layered structure. In mycology, lamellate describes mushrooms with gill-like structures, or lamellae, beneath the cap.

In materials engineering, lamellated designs stack thin sheets to tailor properties. Plywood and laminated veneer lumber use glue-coated veneers to produce strong, flexible boards. Laminated glass sandwiches glass panes with a plastic interlayer for safety. Laminated metal composites and multilayer coatings likewise use lamellae to enhance strength, stiffness, or corrosion resistance.

In geology, lamellated textures refer to thin, parallel layers in sedimentary rocks, formed by alternating deposition of materials and often recording changes in environmental conditions.

Overall, lamelliert or lamellated describes a structural feature defined by layered, plate-like units, a concept applicable in biology, geology, and various branches of materials science. See also lamination, lamina, and lamellar.
