Boron fiber
Boron Fiber is an amorphous elemental boron product which represents the major industrial use of elemental boron. Boron fiber manifests a combination of high strength and high elastic modulus.
A common use of boron fibers is in the construction of high tensile strength tapes. Boron fiber use results in high-strength, lightweight materials that are used chiefly for advanced aerospace structures as a component of composite materials, as well as limited production consumer and sporting goods such as golf clubs and fishing rods.
In the production process, elemental boron is deposited on an even tungsten wire substrate which produces diameters of 4.0 mil and 5.6 mil. It consists of a fully borided tungsten core with amorphous boron.
Boron fibers and sub-millimeter sized crystalline boron springs are produced by laser-assisted chemical vapor deposition. Translation of the focused laser beam allows to produce even complex helical structures. Such structures show good mechanical properties and can be applied as reinforcement of ceramics or in micromechanical systems.
