Abstract
Material and method for securely attaching boron filaments to other like filaments and to a substrate with preservation of the filament integrity for cutting and abrading by coating them with a mixture of matrix metals essentially containing copper, tin and titanium and joining the filaments by the matrix metals and/or to the substrate into an integral structure by liquid-phase-sintering of the matrix metals which grip and adhere the filaments in a strong, tough alloy with the integrity of the filaments essentially preserved. Boron-filament-containing tools for cutting, grinding, abrading, or the like may be fabricated using the materials of the invention and the methods disclosed.
