On the Symposium airbag 2018 (Mannheim, 26-28 November 2018) organized by the Fraunhofer ICT we will present our developments on variant-specific filters for hot gas absorbers as well as D3SM-filters specifically on 27 Novemer 2018. More about D3SM in the following paragraph, click here to be redirected to the airbag 2018 homepage.
D3SM filters represent the latest technology for filtration in hot gas generators. D3SM (depth-defined slit metal) is a sheet metal with openings that are defined in the depth of the material and with that along all three dimensions. As a result, filter rings of D3SM redefine and improve hot gas filtration, control all functional variables and reduce performance-weight. D3SM filters represent an innovative and more capable alternative to the conservative materials knitted mesh, wire mesh or expanded metal – all exhibiting an undefined depth structure and consequently requiring broad tolerance corridors for all performance parameters.
