Crashbox for absorbing impact energy in e.g. car, has sheath composed of fiber reinforced plastic composite material and resting on outer part of deformation section, where sheath has end arranged so as to be rolled on plate during impact
Crashbox for absorbing impact energy in e.g. car, has sheath composed of fiber reinforced plastic composite material and resting on outer part of deformation section, where sheath has end arranged so as to be rolled on plate during impact
The crashbox (1) has a box-shaped deformation section (4) made of metallic sheet forming folds in case of axial buckling of the section. The section has a sheath (5) composed of fiber e.g. carbon fiber, reinforced plastic composite material and mechanically resting, by co-operation of shapes, on an outer part of the section. The sheath has an end arranged so as to be rolled on a support plate (3) during an impact. A foam body is arranged in the section.
