The invention discloses a composite material used for large stage props, comprising a core layer (6), two non-woven fabric layers (5, 7) and two surface layers (1a, 1b) that are sequentially covered on the upper surface and the lower surface of the core layer, and a hoisting point component (4); the hoisting point component (4) is provided with a clamping trough and clamped at the edge of the material mainbody by the clamping trough; a belt hole (14a) used for suspending the material mainbody is arranged on the hoisting point component; the core layer (6) consists of a plurality of honeycomb core blocks (1); a joint belt (10) and a longitudinal reinforced belt and a transverse reinforced belt (2, 3) are arranged between the adjacent honeycomb core blocks (1); and the longitudinal reinforcing belt and transverse reinforcing belt (2, 3) are arranged in the upper surface layer (1a) and/or lower surface layer (1b). The composite material can be assembled to large size, has the advantages of light weight, large flexural rigidity and strength, strong anti-instability capability, anti-fatigue, heat insulation and the like, is easy to be processed, prepared and repaired, has beautiful and soft integer and is insensitive to the environment.
