The invention provides a composite energy absorption device for collision. The composite energy absorption device comprises an extruding part and a bursting part, wherein an accommodating cavity and fiber layers stacked on the side wall of the accommodating cavity are arranged in the bursting part; the accommodating cavity is filled with an energy absorption material; the fiber layers is divided into a silk fiber layer arranged on the inner layer and multiple carbon fiber layers stacked on the outer side of the silk fiber layer; the fiber arrangement angles in the carbon fiber layers are different; the extruding part comprises an extruding rod and an extruding plate; the extruding rod and the accommodating cavity are in interference fit, when the extending rod receives external force, one end of the extruding rod extends into the accommodating cavity and extrudes the energy absorption material, and the other end of the extruding rod is connected with the extruding plate.
