Flexible honeycomb with heart-shaped holes and manufacturing method

The invention relates to a flexible honeycomb with heart-shaped holes and a preparation method. The method comprises the following steps that core strip glue is coated, specifically, the surfaces of flexible thin-layer materials are coated with the core strip glue at equal intervals by adopting a gluing machine; laminating and bonding are carried out, specifically, the multiple layers of flexiblethin-layer materials coated with the core strip glue are laminated and bonded to form a laminated slab according to a mode that every two vertical adjacent layers of core strip glue are laminated andbonded in a staggered mode at equal intervals; hot-pressing solidification are carried out, specifically, the laminated slab is subjected to hot pressing so as to enable the core strip glue at laminating junctions to be solidified; and stretch forming is carried out, specifically, the laminated slab subjected to hot pressing is stretched so as to enable the laminated slab to be stretched in the laminating thickness directi
