Example Embodiment
[0059] Example 1
[0060] The continuous fiber reinforced thermoplastic resin matrix composite material adopts continuous glass fiber reinforced PP prepreg sheet, and the fiber volume content is 50%. The discontinuous fiber reinforced thermoplastic resin is selected from long glass fiber reinforced PP, and the fiber weight content is 40%.
[0061] A laser cutting machine is used to cut the continuous glass fiber reinforced PP sheet according to the design shape, and then lay and assemble. The thickness of the designed main structure is 2.5mm. The assembled sheet was preheated to 160°C with an infrared heating device, and the preheating time was 45s. The preheated sheet was quickly transferred to a forming mold with a mold temperature of 150°C, and the main body of the battery box was formed by clamping and pressing. structure. Then, long glass fiber reinforced PP resin was used to injection-mold the battery box assembly and reinforcing rib structure, and the injection temper...

[0062] Example 2
[0063]The continuous fiber reinforced thermoplastic resin matrix composite material selects unidirectional carbon fiber reinforced PA66 prepreg sheet and unidirectional glass fiber reinforced PA66 prepreg sheet, and the fiber volume content is 55%. The discontinuous fiber reinforced thermoplastic resin uses long glass fiber reinforced PA66, and the fiber weight content is 45%.
[0064] High-speed robotic cutting equipment is used to cut unidirectional prepreg sheets according to the design requirements, and lay them for assembly. The inner surface of the box is laminated with glass fiber reinforced PA66 prepreg sheets, and the rest of the layups are made of carbon fiber reinforced PA66 prepreg sheets. , The thickness of the main structure of the designed battery box is 2.0mm. The assembled thermoplastic sheet is preheated to 270°C by electromagnetic heating, and the preheating time is 50s. The preheated sheet is quickly transferred to the forming mold with ...
