The invention relates to an internal torsion honeycomb structure material and a preparation method thereof, and belongs to the technical field of honeycomb materials. The internal torsion honeycomb structure material is composed of a plurality of internal torsion hexagonal honeycomb structure cell units which are arranged in a topological array mode, and the cross section of the outer layer cell wall of each internal torsion hexagonal honeycomb structure cell unit is in a regular hexagon shape. The inner-layer cell wall of each internally-twisted hexagonal honeycomb structure cell unit consists of twisted curved surfaces which are connected in sequence, and the adjacent internally-twisted hexagonal honeycomb structure cell units share the outer-layer cell wall. According to the invention, the inner-layer cell wall of the hexagonal honeycomb is twisted, and the energy absorption characteristic and the specific stiffness performance of the honeycomb structure are regulated and controlled by adjusting the proces
