Specialty Materials Inc. (Lowell, Mass., USA) is featuring its line of boron and silicon carbide fibers, boron prepregs and boron nanopowder. Boron fiber is used in aerospace and sporting goods applications. Boron/graphite hybrid preforms reportedly enhance compression, impact and open-hole compression properties. Silicon carbide fiber has high-temperature mechanical properties that increase strength and stiffness at elevated temperature. Boron nanopowder is being developed to provide higher critical current densities in MgB2 superconductors, and FRA (fiber-reinforced aluminum) is being developed for applications where wear resistance is critical.
