Development of High-Performance FRP Crash Boxes~A Report on FRP Working Group's Activity Evaluation of Reliability
Published May 23, 2007 by Society of Automotive Engineers of Japan in Japan
Event: JSAE Spring Conference
In our WG, a research on the energy absorption of FRP (Fiber-Reinforced Plastic) tubes has been conducted. Based on this, we applied the FRP tubes as crash absorbers for vehicles. Specifically, these FRP tubes are utilized as the crash boxes because they effectively absorbed energy generated at low impact speed. This is due to its unique energy absorption properties. These FRP crash boxes are lightweight and cheap since its resin is made of thermoplastic polypropylene and these crash boxes are made of the continuous strand mat type of fibers. Additionally, these FRP crash boxes can be recycled.
We initially gathered the data on the energy absorption properties of some currently used commercial crash boxes which are made of steel. Then we developed the crash boxes made from the glass fiber-reinforced plastics based on our investigation. After this, we present the report on the reliability evaluation of our FRP crash boxes.
