Foam material reinforcing method

The invention provides a foam material reinforcing method, and belongs to the technical field of material reinforcing. The reinforcing method comprises the following steps: firstly, forming a first reinforcing layer in the foam material, then forming a second reinforcing layer in the foam material, then cutting along a third cutting surface to obtain a third foam sheet, and in the third foam sheet, connecting the first reinforcing layer and the second reinforcing layer in a matched manner to form a grid structure. The compression resistance of the foam material can be effectively enhanced; the second reinforcing layer formed by the method is of a continuous structure and can effectively bear and transmit bending and shearing loads, so that the bending resistance and the shearing resistance of the foam material are improved. The reinforcing method is simple in operation of each process, directly uses the integrally formed large-size foam raw material, is suitable for automatic, batch and rapid production, is e
