The utility model discloses a box body for a light aviation dining car, and belongs to the technical field of aviation service equipment. Wherein the box body comprises a frame of the box body and wall plate assemblies arranged at the periphery of the frame; the wall plate assembly comprises an upper wall plate, a lower wall plate, a left wall plate, a right wall plate, a front wall plate and a rear wall plate. The end of one vertical end of the left wall plate is hinged to the frame. A plurality of clapboards are arranged in the middle of the frame; the wall plate assemblies and the profilesforming the frame are all composite fiber layer plates. Each composite fiber layer plate comprises a reinforcing fiber layer, hemp plant fiber layers arranged on the upper layer and the lower layer ofthe reinforcing fiber layer, and reinforcing fiber layers arranged outside the hemp plant fiber layers respectively. According to the box body, the reinforced fibers and the plant fibers form the composite fiber laminate with an interlayer hybrid structure, so that the aims of light weight and low cost can be fulfilled while the mechanical property requirement of an aviation dining car is met, the overall weight of the box body is reduced, the mechanical supporting strength is improved, and the effects of flame retardance and heat preservation can be achieved; and the water absorption is reduced, so that a waterproof effect is achieved.
