Development of High Performance FRP Crash Boxes (A Report on FRP Working Group Activity: Stochastic Evaluation of Energy Absorption Performance)

摘要

We have been researching the energy absorption of FRP tubes so far in our WG activity. Based on such a valuable knowledge, we are trying to apply the FRPs as crash absorbers for vehicles. These FRP crash boxes are light weight and low-priced products because the resin of these crash boxes is the thermoplastic polypropylene and the fiber is the continuous strand mat. We had initially surveyed the energy absorption properties of FRP crash box. And the reliability of FRP crash box is investigated by experimental and numerical technology.
