Crash-structure made of fibre reinforced composite material and uses of such a structure

摘要

The fiber reinforcement comprises a hollow outer body (1) with an internal beam section (2) extending in the longitudinal direction (Z). Increased structural integrity is achieved by reinforcing elements connecting the beam section and walls at their contact points (10,11). Preferred Features: Reinforcing elements comprise stitching fibers and are inserted into the body wall so that they pass either through the wall thickness or run circumferentially and in the longitudinal direction. Spacing of the reinforcing elements can be varied to determine the impact energy absorption of the structure. The beam section and hollow outer body may be sewn together by tufting or the reinforcing fibers are sewn into the outer body wall by tufting.
