Convex honeycomb core

The utility model discloses a convex honeycomb core. The convex honeycomb core comprises a plurality of first waveform honeycomb plates and a plurality of second waveform honeycomb plates, the first wave-shaped cellular board is integrally formed by a plurality of first wave-shaped units, and the second wave-shaped cellular board is integrally formed by a plurality of second wave-shaped units; the first convex hole cambered surface is matched with the fourth convex hole cambered surface in position, and the second convex hole cambered surface is matched with the third convex hole cambered surface in position; the first wave-shaped cellular board and the second wave-shaped cellular board are stacked in a staggered mode to form a cellular cavity with a convex section. The convex honeycomb core forms a honeycomb structure with a convex section through staggered stacking of a first waveform honeycomb plate and a second waveform honeycomb plate; according to the hexagonal honeycomb, the limitation that a conventio
