Copper-Coated Steel Fibers: Hybrid Conductive Reinforcements for Advanced Composites microfiber concrete
1. Product Structure and Interfacial Design 1.1 Core-Shell Framework and Bonding Device (Copper-Coated Steel Fibers) Copper-coated steel fibers (CCSF) are composite filaments consisting of a high-strength steel core covered by a conductive copper layer, developing a metallurgically adhered core-shell architecture. The steel core, typically low-carbon or stainless steel, supplies mechanical effectiveness with tensile toughness exceeding…
