Beschreibung
Zusammenfassung:	A consolidated, reinforced composite member is made from a matrix mixture including a consolidation shrinkable discontinuous material, for example ceramic particles, and a particulate inorganic filler which will exhibit net expansion relative to the discontinuous material, the mixture being interspersed about reinforcing fibers to provide a preform. Subsequent consolidation of the preform can be conducted at ambient pressure, without application of additional pressure. The member may be an airfoil shaped strut (10), useful in a gas turbine engine hot section, which is made by disposition of plies 22 formed from the matrix mixture and fibres, e.g. fabric, about forming blocks 24, e.g. of aluminium, the assembly being placed within forming dies (26A, 26B) and pressure being applied while the assembly is heated. The resulting preform is sintered in a furnace to a consolidation temperature, without external pressure being applied. The ceramic particles are preferably alumina and the filler may be pyrophillite.
