Raw material impregnated fiber frame for high-molecular rigid foam production and forming process

The invention belongs to the technical field of foam fiber frames, particularly relates to a raw material impregnated fiber frame for high-molecular rigid foam production and a forming process, and provides the following scheme aiming at the problems that an existing fiber frame is poor in performance and cannot meet the use requirements of toughness, fire prevention, oxidation resistance and the like in the long-term use process: the raw material impregnated fiber frame comprises X-direction lines and Y-direction lines, the X-direction lines and the Y-direction lines are connected in a staggered mode to form a fiber frame, the Y-direction lines are arranged in a bent mode, the outer included angle of each Y-direction line forms a, the inner included angle of each Y-direction line forms b, a is larger than 75 degrees and smaller than 90 degrees, b is larger than 120 degrees and smaller than 130 degrees, Z-direction lines are arranged at the two ends of the fiber frame in a staggered mode, and the X-direction
