Abstract
An article includes a body and at least one 3D-printable conductive composite segment in mechanical communication with the body. The body includes a first material and the at least one conductive composite segment includes a matrix material, a plurality of carbon nanotubes, and conductive additives. The conductive additives include a plurality of metallic particulates, a plurality of graphitic particles or a combination thereof.

3 more elements
A method for monitoring structural integrity of an object, comprising:
- measuring a conductivity value of at least one 3D printable conductive composite segment that is in mechanical communication with the body of an article, wherein the at least one conductive composite segment comprises
- a matrix material,
- a plurality of carbon nanotubes, and
- a plurality of conductive additives comprising metallic particulates, graphitic particles or combinations thereof;
- comparing the measured conductivity value to a known conductivity value;
- determining whether a difference between the measured conductivity value and the known conductivity value falls within a predetermined threshold value;
- and
- generating an alarm if the difference is within the predetermined threshold value.
