Abstract

Se desarrollaron fluidos electrorreológicos que contienen fundamentalmente un silicato metálico hidratado exento de aluminio, con estructura laminar, un dispersante y un medio de dispersión inerte y aprótico. El silicato metálico hidratado pertenece preferentemente al tipo de la kenyaita, de la magadiita y/o de la canemita. El medio de dispersión es preferentemente un aceite de silicona con un intervalo de viscosidades entre 0,5 y 1000 mPas o bien un aceite mineral o un aceite de parafina con un intervalo de viscosidades entre 0.1 y 1000 mPas. El silicato metálico hidratado se añade al líquido electrorreologico en una concentración de -50 en peso.
