Boron Fiber

Name:
Boron Fiber
Detailed information:
A vapor-deposited filament made by deposition of boron on a heated tungsten wire. The filament is 0.004 inch in diameter, while the wire is only 0.0005 inch. Tensile strength 350,000–450,000 psi, elastic modulus 55 million psi, upper temperature limit in oxidizing atmosphere 250C. Used in composites with epoxy resins for aircraft and space applications. The fibers can be woven into fabrics.
