EPDM rocket motor insulation

   
   

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.

Uma novela e um formulation melhorado de EPDM para um motor contínuo do foguete do propulsor são descritos wherein os componentes do monomer do hexadiene EPDM são substituídos por componentes do norbornene do alkylidene, e, com ajuste apropriado de aditivos se curando e outros, as características rheological e físicas funcionalmente requeridas são conseguidas com a compatibilidade desejada com qualquer de um plurality de materiais de enchimento contínuos, por exemplo, silicone do pó, fibras do carbono ou fibras do aramid, e com adesão apropriada e características estendidas do armazenamento ou do shelf-life.
