摘要

This study analyzes the crashworthiness of a light aircraft that is constructed from composite materials. The finite element method is employed to conduct dynamic impact simulations on carbon fiber composite fuselages. The results show that the safe impact speed for an aluminum alloy cockpit crashed at a 30 degrees impact angle is 9.59 m/s, but a cockpit made of composite material can withstand a speed greater than 18.05 m/s. The safe impact angle for an aluminum alloy cockpit is 16.56 degrees, but that for a composite cockpit is 84.9 degrees. The safety crash zone for a composite material cockpit is 160% greater than that for an aluminum alloy cockpit.
