Preferably, the insert is integrally formed with the honeycomb structure by a co-curing process.
Preferably, the insert and the honeycomb structure are glued to each other.
Preferably, the chamfer degree is 100 degrees or 130 degrees.
Preferably, a dimension of the insert head portion in an axial direction of the insert shaft portion is the same as a dimension of the honeycomb outer panel in the honeycomb structure in the direction.
The utility model also provides a honeycomb structure, honeycomb structure includes as above the embedment.
The utility model also provides an aircraft, aircraft include as above honeycomb.
The utility model discloses an in the embedding piece, the confession connecting piece of embedding piece head gets into the department and has the chamfer, and this chamfer can make the connecting piece get into the embedding piece after, holds to the embedding piece completely for whole honeycomb's surface flushes, has solved for honeycomb's among the prior art surface irregularity, influences the problem of honeycomb's performance.
