1.1 Core-Shell Structure and Bonding Device

(Copper-Coated Steel Fibers)

Copper-coated steel fibers (CCSF) are composite filaments including a high-strength steel core enveloped by a conductive copper layer, forming a metallurgically bonded core-shell style.

The steel core, typically low-carbon or stainless-steel, gives mechanical robustness with tensile toughness surpassing 2000 MPa, while the copper finishing– usually 2– 10% of the complete size– imparts exceptional electric and thermal conductivity.

The interface between steel and copper is vital for performance; it is crafted via electroplating, electroless deposition, or cladding procedures to make sure strong bond and marginal interdiffusion under operational tensions.

Electroplating is the most usual approach, supplying accurate thickness control and uniform coverage on continuous steel filaments attracted through copper sulfate baths.
