Abstract:
The invention relates to new amorphous, high-strength SiBN(C) fibers which are at the same time resistant to high-temperature creep, their production and use. The fibers have a strength at room temperature of >2.5 GPa, a modulus of elasticity of >250 GPa and a creep value m of from 0.4 to 1 (in accordance with standard BSR test, 1 hour, 1400.degree. C.).
