Design of an Impact Attenuator Using Alternative Material

WitrynaTeams building a Type 11 impact attenuator must support their use of Dow Impaxx® 700 by bringing a receipt for the material to technical inspection. The technical inspectors may choose to verify the dimensions and the material and have the authority to conduct any measurements, inspections or tests they feel are necessary. WitrynaDescription. This Variable Attenuator DC Block (VATTENDCB) is a one input, one output attenuator that operates with a variable attenuation range that can be user selected via a potentiometer control. This unit provides between 3 – 37dB (typical) of attenuation in a miniaturized housing. The frequency response covers the GPS L1/L2 …

Crumple zones, crush zones, or crash zones are a structural safety feature used in vehicles, mainly in automobiles, to increase the time over which a change in velocity (and consequently momentum) occurs from the impact during a collision by a controlled deformation; in recent years, it is also incorporated into trains and railcars. WitrynaFigure 2: Geometrical configuration of the impact attenuator The manufacture of the impact attenuator was obtained by hand lay up of pre-impregnated composite layers and autoclave curing at 135 °C and 7 bar applied pressure. In particular, the composite material is plain weave prepreg with carbon fibres and epoxy resin [3]. Mechanical
