PROCEDE D'OBTENTION D'UNE PREFORME DE FIBRES ET DISPOSITIF A FAIBLE INERTIE THERMIQUE POUR SA MISE EN OEUVRE

The process comprises placing fibers with less quantity of resin in a preforming tool comprising an element (14), raising the temperature of a porous preform (10) to obtain the polymerization of the resin, maintaining the fibers against the preforming element until the temperature of the preform dec...

Beschreibung
Zusammenfassung:	The process comprises placing fibers with less quantity of resin in a preforming tool comprising an element (14), raising the temperature of a porous preform (10) to obtain the polymerization of the resin, maintaining the fibers against the preforming element until the temperature of the preform decreases below threshold temperature. The increase in temperature is obtained by dynamically transferring heat between a heat source and the preform. Porosity of the preforming tool is adjusted in order to be permeable to coolant fluid. An independent claim is included for a device for obtaining a porous preform from fibers with less quantity of resin.
