Recent studies on processing, physical and thermal properties of Blackglas confirm an increasing interest in its utilization as a low-cost matrix in heat resistant composites. Blackglas results from pyrolysis under inert conditions of a siloxane monomer polymerized with a catalyst to produce a refractory silicon oxycarbide. In the present study the elastic behavior of unidirectional composites with matrix derived from cured polysiloxanes and reinforced with SiC or alumina fibers (Nicalon or Nextel, respectively) is investigated at temperatures up to 1300DGC in order to assess limits of their potential utilization as a structural material in air environment.
