Development of High-Performance FRP Crash Boxes~FRP Working Group Activity Report on the Evaluation of Energy Absorption Performance

Event: JSAE Autumn Conference
To date, we have been researching the energy absorption of FRP tubes in our WG activity. With such valuable knowledge, we are attempting to apply the FRPs as vehicle crash absorbers. In particular, because of the peculiar energy absorption properties of FRP tubes, these FRPs are useful for crash boxes which absorb energy generated at low impact speeds. These FRP crash boxes are lightweight and low-priced products because the resin is thermoplastic polypropylene and the fiber is continuous strand mat. Additionally, FRP crash boxes may be recycled. We initially surveyed the energy absorption properties of a few existing commercial crash boxes made from steel. Subsequently, we developed crash boxes made from glass-fiber-reinforced plastics as a result of the above-mentioned survey. We report the results from our assessment of the FRP crash boxes that we developed.
