Metallic Fibers
Metallic Fibers
Metallic fibers are a type of manufactured fiber composed of metal, metallic alloys, plastic-coated metal, or metal-coated plastic. These fibers may also feature a core completely covered by metal. Metallic fibers have a rich history, tracing back to ancient times when gold and silver were used to create decorative yarns for fabric.
Historical Context
The use of metallic fibers dates back to antiquity, where they found applications in the textiles of kings, leaders, and nobility. The decorative use of these fibers in clothing signified high status and wealth. Over time, advancements in technology have allowed for the production of metallic fibers on a much larger scale.
Production Methods
The production of metallic fibers can be achieved through various methods, including:
- Shaving: This involves shaving fibers from a larger stock.
- Casting: Casting directly from molten metal to form fibers.
- Growth Around a Seed: Growing fibers around a seed material.
In the modern era, multiple fibers can be woven or intertwined to form larger strands, enhancing their structural capabilities.
Applications
Metallic fibers are used across a wide range of industries due to their unique properties. These applications include:
- Textiles: Enhancing the aesthetic and functional properties of fabrics.
- Conductive Textiles: Used in conductive textiles where they provide electrical conductivity. These can be made by wrapping metallic fibers around a non-metallic core or by coating them with metal.
- Composite Materials: In composite materials, metallic fibers provide strength and durability at cryogenic temperatures, which is advantageous over non-metallic fibers.
- Industrial Uses: Including the production of wire rope and other materials requiring high tensile strength.
Technological Advancements
The development of fine metallic fibers has been driven by industrial advancements. By 1964, companies like Brunswick were producing fine metal fibers as small as 1 μm from 304 stainless steel. The establishment of large-scale production facilities in the mid-20th century has facilitated the widespread use of metallic fibers in various technological applications.
