Hybridization effect on energy absorption capacity of composite crash boxes

Polymer Composites, Volume 45, Issue 13, Page 12349-12361, 10 September 2024.
Production and post‐test images of hybrid crash boxes. Abstract Crash boxes are safety elements generally made of metallic materials and mounted on the chassis of vehicles to prevent possible injuries to driver and passengers by absorbing the energy generated during a collision and ensuring integrity of vehicle. In order to save fuel and reduce harmful
