To address the problem of crash damage characteristics and crashworthiness optimization of composite un-manned boats,this paper firstly carries out experimental research on the mechanical properties of composite materials for un-manned boats and obtains the basic mechanical properties parameters of composite materials.On the basis of ensuring the ra-tionality of material parameters,numerical simulation studies on the crash worthiness of composite unmanned boats under different composite lay-up angles are carried out to obtain the collision force,displacement,acceleration and energy absorp-tion of the main components of composite unmanned boats,so as to determine the material lay-up scheme of composite un-manned boats with better crash worthiness.This provides the basis for the analysis of the collision of the composite un-manned boat and the optimization of the crash worthiness of the unmanned boat.
