serrésused

Serrésused is a term used in materials science and design to describe the deliberate reuse of serrated surface features to enhance bonding and mechanical interlocking in composite assemblies. The concept combines serration geometry with principles of reuse and circular economy, aiming to preserve functional surface patterns across salvaged parts rather than discarding them for smooth, newly manufactured interfaces.

The term emerged in design discourse in the early 2020s as researchers and practitioners explored sustainable manufacturing and modular reuse. It is sometimes discussed in design fiction and speculative engineering as a way to imagine how salvaged components with serrated interfaces could be integrated into new products, reducing waste while enabling secure assemblies.

Key features of serresused interfaces include standardized serration patterns (such as pitch and tooth geometry) and clear compatibility requirements for mating surfaces. Manufacturing and reprocessing methods must preserve edge integrity to maintain interlocking capability. The mechanism relies on a combination of mechanical interlock and friction, which can improve shear resistance and distribute loads across the interface in certain conditions. Proper tolerancing and surface preparation are essential to ensure reliable engagement after reuse.

Applications are envisioned across sectors that emphasize sustainability and modularity, including aerospace and automotive components recovered from scrap or end-of-life parts, consumer electronics housings with modular serrated joints, and architectural elements using salvaged metal sheets.

Limitations include strict tolerance control, potential corrosion at serrated interfaces, inspection and repair challenges, and the need for standardized serration geometries to enable cross-part reuse. See also: serration, knurling, mechanical interlocking, circular economy.
