Elastomerkoblinger

Elastomerkoblinger is a class of elastomeric materials proposed for use as mechanical couplings that combine high elasticity with tunable damping. The term blends elastomer with kobling, a word used in several Germanic languages for coupling, signaling the material’s function as an interface element between moving parts.

Composition and microstructure: It typically consists of a polymeric elastomer matrix (such as silicone, fluorosilicone, or ethylene-propylene-diene monomer) with dispersed damping fillers or a reinforcing phase to tailor viscoelastic properties. Crosslink networks are formed by vulcanization or peroxide curing. Some formulations incorporate mineral fillers or micro-structured particles to adjust stiffness and energy dissipation.

Properties: Elastomerkoblinger formulations aim for a balance of high elasticity, broad damping spectrum, and good thermal and chemical resistance. The materials exhibit viscoelastic behavior with a loss tangent that can be tuned by composition and temperature. They typically show low permanent set under cyclic loading but may experience creep at higher loads.

Processing and performance: Processed by standard elastomer techniques such as molding or extrusion; curing schedules depend on the polymer system. The resulting interfaces can be shaped to fit shafts, flanges, or housings, providing vibration isolation and load transfer without rigid backlash.

Applications and status: The concept is discussed in materials-science literature and niche engineering practices as a potential alternative to metal springs or discrete dampers in automotive, industrial machinery, and seismic isolation. Not yet standardized; performance depends on exact formulation, aging, and operating environment; ongoing research seeks to optimize durability and cost.
