The invention relates to fiber reinforced resin matrix composite processing, belongs to the field of high polymer material processing, and discloses a processing method of a continuous fiber reinforced resin matrix composite. According to the method, a gradient cured resin body is dipped to fiber cloth; then the first time of curing is generated at a first curing temperature; then materials are shorn; after the materials are stacked into a three-dimensional target shape, pressurizing and heating are carried out, and generation of the second time of curing reaction is promoted; and finally a solid product is obtained. According to the method, different kinds of resin and the fiber cloth of multiple materials are continuously compounded; the composite preparation time which originally ranges from 5 h to 6 h is shortened to be within 5 min, and forming efficiency is greatly improved; the restrictive bottlenecks of high cost and low efficiency existing in large-batch application of the continuous fiber reinforced resin matrix composite to the civil field such as automobiles are broken through; manual procedures are reduced; product consistency is effectively improved; and the large-batch manufacturing requirement is met.
