Abstract

Formation d'un produit tubulaire élastomère renforcé par des fibres orientées. On pompe 11 un progéniteur de polymère liquide ayant une viscosité de 20 à 4 000 cPo et un temps de durcissement de 1/2 à 3 secondes à 150-250 degrés C, à travers une extrudeuse 10 parcourue par un fluide chauffant 17 pour amorcer la réaction de durcissement, en faisant tourner au moins une des surfaces de formage 19, 21 pour orienter les fibres, et on chauffe le produit 15 dans un four 13. Fabrication de tubes thermodurcissables.
