Embodiment 1
[0055] Such as figure 1 as shown, figure 1 It is a schematic cross-sectional structure diagram of the laminated board in Example 1.
[0056] Both the surface layer and the bottom layer are continuous fiber-reinforced thermoplastic sheets. The surface layer and the bottom layer are made by the following method: spreading continuous glass fibers, compounding them with extruded molten polypropylene resin, and then rolling to obtain continuous fiber-reinforced thermoplastic sheets. The prepreg tape, in the prepreg tape, the mass percentage of continuous fiber is 40%, the continuous fiber reinforced thermoplastic prepreg tape is stacked and laid, put into a hot press, and then the temperature is 170 ℃, the pressure is 2MPa Under certain conditions, the continuous fiber-reinforced thermoplastic prepreg tape is hot-pressed into a sheet for 20 minutes, and then cold-pressed for 30 minutes to obtain a continuous fiber-reinforced thermoplastic sheet.

Embodiment 2
[0063] Such as figure 2 as shown, figure 2 It is a schematic cross-sectional structure diagram of the laminated board in Example 2.
[0064] The surface layer, the bottom layer and the inner layer are all continuous fiber reinforced thermoplastic sheets. The surface layer, the bottom layer and the inner layer are made by the following method: the continuous glass fiber is spread out, compounded with extruded molten polyethylene resin, and then rolled , to obtain a continuous fiber reinforced thermoplastic prepreg tape, in the prepreg tape, the mass percentage of continuous fiber is 40%, the continuous fiber reinforced thermoplastic prepreg tape is superimposed and laid, put into a hot press, and then at a temperature of Under the conditions of 160°C and a pressure of 2 MPa, the continuous fiber reinforced thermoplastic prepreg tape was hot-pressed into a sheet for 30 minutes, and then cold-pressed for 40 minutes to obtain a continuous fiber-reinforced thermoplastic sheet. T...
Embodiment 3
[0071] Both the surface layer and the bottom layer are continuous fiber-reinforced thermoplastic sheets. The surface layer and the bottom layer are made by the following method: the continuous glass fiber is spread out, compounded with extruded and molten polycarbonate resin, and then rolled to obtain continuous fiber reinforcement. Thermoplastic prepreg tape, in the prepreg tape, the mass percentage of continuous fiber is 40%, the continuous fiber reinforced thermoplastic prepreg tape is stacked and placed in a hot press, and then the temperature is 230 ° C, the pressure is Under the condition of 2MPa, the continuous fiber-reinforced thermoplastic prepreg tape was hot-pressed into a sheet for 20 minutes, and then cold-pressed for 30 minutes to obtain a continuous fiber-reinforced thermoplastic sheet.
[0072] The preparation method of the intermediate layer is as follows: the intermediate layer includes a first core layer and reinforcing layers located on both sides of the fir...
