A stabilizable preform precursor for composites is provided. The preform precursor has at least one layer of a structural fabric comprised of reinforcing fibers wherein at least one of the layer(s) of structural fabric has integrated therein one or more stabilizing fiber(s) that dissolves at a dissolution temperature in a resin for infusing into the structural fabric to make the composite. The stabilizing fiber stabilizes the stabilizable preform precursor when the stabilizable preform precursor is subjected to an elevated temperature.
Cette invention concerne un précurseur de préforme stabilisable. Ce précurseur de préforme comporte au moins une couche de tissu structural constitué de fibres renforcées, une au moins des couches de tissu structural renfermant une ou plusieurs fibres de stabilisation qui se dissolvent à la température de dissolution en une résine qui infuse dans le tissu structural et forme le composite. Lesdites fibres stabilisent le précurseur de préforme stabilisable lorsque ce dernier est soumis à une élévation de température.
