Abstract
The production technology and properties of porous preforms for the reinforcing of composite materials are discussed in this paper. The preforms were produced by the mixing of alumina “Saffil” fibres with inorganic and organic binders followed by forming, drying and firing. Applying standard methods, the effect of porosity on the Tc hardness, tensile strength and bending strength were investigated. The preforms produced showed good properties, making possible their infiltration by liquid metal alloys. Microscopic investigations revealed good joints between the fibres. Ceramic preforms of 75–90% porosity were produced, the technology making possible the production of preforms from different reinforcing fibres.
