摘要: Un systeme de securite automatique pour automobiles, et notamment un protege-genoux, est place sous la colonne du volant, devant les genoux. An automatic safety system for and in particular a knee pad is placed under the column of steering wheel, front knees. Afin d'assurer l'absorption d'energie, le protege-genoux comprend noyau d'absorption d'energie rempli d'une pluralite granules en resine thermodurcie. To ensure energy absorption, bolster includes absorption core filled with plurality thermoset resin. Le agence entre une piece brute matricee metal ou plastique rembourrage mousse. The arranged between blank stamped from or plastic foam padding. Chaque granule contient melange extrude resines thermodurcies microspheres, enrobe adhesive. Each contains an extruded mixture resins coated adhesive Ces peuvent se composer thermodurcie, telle qu'une polyester epoxyde, des vinylester polyurethanne, phenolique, comprendre microspheres pre-expansees organiques, inorganiques verre. Such may be composed resin such as epoxy, polyurethane resins, phenolic resin, include pre-expanded organic inorganic glass. Alternativement, thermoplastiques non expansees mais susceptibles d'etre thermiquement agent gonflant liquide, si l'on veut expanser granules. Alternatively, non-expanded thermoplastic but thermally expanded liquid blowing agent, if one wants to expand additif durcissants etre ajoutes au faciliter durcissement pendant l'etape finale renforcement, d'autres additifs afin d'ameliorer son extrudabilite proprietes additive curing added facilitate hardening during final stage building, other additives improve its extrudability properties
