[0016] Hereinafter, the present invention will be described in more detail with examples in conjunction with the drawings:
[0017] The embedded metal plate of the metal connector is partially embedded between the sandwich foam and the composite material plate; the integrated molding technology is used to solidify the composite material sandwich plate and the metal connector; the structure of the two metal connectors is different; Lap the two metal connectors together, and then use glue and welding to strengthen. The embedded metal plate of the metal connector is partially embedded between the sandwich foam and the composite material plate, using a co-curing wedge technology. In the pre-embedded metal plate part of the metal connector, the surface of the metal plate is provided with well-designed perforations, so that the composite material plate forms a nail-shaped protrusion at the perforation, increasing the connection strength. The surface of the metal connector contacting t...
