Carbon Fiber Automotive Crash Boxes: Design and Testing for Front and Rear Impact Absorption
Engineering guide to carbon fiber automotive crash box design, testing, and production. Analysis of specific energy absorption (60–120 kJ/kg), trigger mechanisms (45° chamfer, groove, tulip designs), cross-sectional geometry optimization, and manufacturing processes (braiding+RTM, filament winding, compression molding). Includes OEM case studies from BMW, Audi, Volvo, BYD, and NIO with crash test data and cost analysis.
