Title
(EN) NOVEL EPDM ROCKET MOTOR INSULATION
(FR) NOUVELLE ISOLATION PAR EPDM D'UN MOTEUR-FUSEE
Abstract
(EN)
A novel and improved EPDM formulation for a solid propellant rocket motor is described wherein hexadiene EPDM monomer components are replaced by alkylidene norbornene components and with appropriate adjustment of curing and other additives functionally-required rheological and physical characteristics are achieved with the desired compatibility with any one of a plurality of solid filler materials, e.g. powder silica, carbon fibers or aramid fibers, and with appropriate adhesion and extended storage or shelf life characteristics.
(FR)
L'invention concerne une nouvelle préparation améliorée d'EDPM pour un moteur-fusée à poudre dans laquelle les composants monomères EPDM d'hexadiène sont remplacés par des composants d'alkylidène norbornène. Un réglage adéquat du durcissement est effectué et d'autres additifs rhéologiques nécessaires au fonctionnement sont obtenus garantissant des caractéristiques physiques. On assure une compatibilité avec toute autre matière de charge solide, telle que le silicium en poudre, les fibres de carbone ou les fibres d'aramide et une adhérence adéquate ainsi que des propriétés de stockage ou de durée de conservation prolongées.
