Faserstrang

Faserstrang is a term used in materials science and textiles to denote a single continuous strand of material consisting of one or more aligned filaments. It may be a monofilament, consisting of a single filament, or a multifilament strand, consisting of many filaments bound together. Faserstränge are produced by extrusion of polymers for synthetic fibers or by drawing and twisting natural fibers. In textile production they serve as the base element for yarns after twisting or interlacing, while in composite manufacturing they are used as reinforcement in resins to create fiber-reinforced composites. The diameter of a Faserstrang depends on material and process, typically in the micrometer range for filaments, up to larger values for thicker strands.

Mechanical properties such as tensile strength, modulus and elongation at break depend on the material, cross-section and internal structure. Common materials include glass fibers, carbon fibers, polyester, nylon, aramids and natural fibers such as cotton or flax. Handling characteristics differ: monofilaments are stiff and exhibit low elongation, while multifilament strands can be twisted into yarns or braided into ropes. In practice, the term is often used in German-language technical literature and is closely related to, but distinct from, Filament, Monofilament and Garn (yarn). Faserstränge can be prepared and processed further into textiles, reinforcement architectures, or composite materials depending on the intended application.
