1-24. (canceled)
A structure comprising:
- a first facesheet and a second facesheet, each comprising a composite laminate;
- a core comprising a first core segment and a second core segment, the core being joined to and sandwiched between the first facesheet and the second facesheet, a joint being between the first core segment and the second core segment, the joint being sandwiched between the first facesheet and the second facesheet;
- and
- an arrestment feature configured to arrest propagation of an inconsistency, the arrestment feature wrapping at least partially around two sides of at least one of the first core segment and the second core segment at about the joint, and the first face sheet and the second facesheet each extending over the arrestment feature.

A structure comprising:
- a first facesheet and a second facesheet, each comprising multiple plies of a composite material;
- a segmented core sandwiched between and joined to the first facesheet and second facesheet, the segmented core including a plurality of core segments spliced together along corresponding joints between their mutual edges;
- and
- a plurality of arrestment features, wherein ones of the plurality of arrestment features extend along ones of the corresponding joints, wherein all of the plurality of arrestment features are sandwiched between the first facesheet and the second facesheet, and wherein all of the plurality of arrestment features are configured to arrest propagation of an inconsistency in the structure.
