[0025] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0026] Reference Figure 1-4A resin SMC prepreg sheet includes a substrate 1: a reinforcement unit 2 is arranged on the upper side of the substrate 1, a reinforcement layer 3 is arranged on the upper side of the reinforcement unit 2, a corrosion-resistant layer 4 is fixedly connected to the upper side of the reinforcement layer 3, and the corrosion-resistant layer 4 is made of polytetrafluoroethylene material, wherein the corrosion-resistant layer 4 increases the corrosion resistance of the SMC sheet.

[0027] The reinforcement unit 2 includes a filling layer 201, which is fixedly connected to the upper side of the substrate 1, a fixed block 203 is fixedly connected to the inner side of the filling layer 201, and a reinforcement cross bar 202 is fixedly connected to the outer side of the fixed block 203. The inner sides of the filling layer 201, the reinforcement layer 3 and the corrosion-resistant layer 4 are fixedly connected to the reinforcement vertical bar 204. The filling layer 201 is made of rubber material, and the reinforcement cross bar 202 and the reinforcement vertical bar 204 are both made of polyvinyl chloride material. The number of the reinforcement cross bar 202 and the reinforcement vertical bar 204 is set in multiples, and the reinforcement layer 3 is made of cellulose acetate material. The lower end of the reinforcing vertical rod 204 passes through the outside of the fixed block 203. The filling layer 201 has the same thickness as the reinforcing layer 3. There are multiple fixed blocks 203, which are made of polypropylene material. When in use, the fixed block 203 and the reinforcing cross bar 202 are used to initially buffer the external impact force, and the SMC sheet is reinforced again through multiple reinforcing vertical rods 204. Then, the filling layer 201 and the reinforcing layer 3 are used to reinforce the SMC sheet, increase the overall compressive resistance of the sheet, and avoid damage to the sheet caused by external impact force.

[0028] Working principle: When in use, the SMC sheet is initially reinforced by reinforcing the horizontal rod 202 and the vertical rod 204, and then the sheet is reinforced again by reinforcing the vertical rod 204. Then, the filling layer 201 and the reinforcement layer 3 are used to increase the compressive performance of the SMC sheet to prevent the SMC sheet from being damaged by external impact.
