摘要:
The present disclosure relates to the active initiation of incident energy-dissipating material from a structure surface coating as a counter measure response for the protection of a structure surface. The active initiation is triggered at a predetermined area or areas on a targeted structure surface in response to incident directed energy sensed on a target surface.

The present disclosure relates to the passive initiation and release of incident energy-dissipating material from locations on an incident energy target surface as a counter measure response for the protection of a platform. The response is activated over a predetermined area or areas on an incident energy target surface in response to an incident directed energy sensed on a target surface.
摘要:
Apparatus and methods to provide a surface having a tunable emissivity are disclosed. An example method includes tuning a characteristic of one or more resonators in a material to change an absorption of radiation by the one or more resonators and to change an amount of destructive interference caused by the material.
摘要:
A transducer for stimulating an article under test with ultrasonic vibration may include a transducer body having a transmitting face and configured to generate ultrasonic vibration through the transmitting face, and an couplant mounted on the transmitting face, the couplant having a multiplicity of vertically aligned carbon nanotubes extending therefrom in a direction substantially normal to the transmitting face.
摘要:
A composite bonded structure with integral stress sensing and bond evaluation system incorporates a bonded structure having a first component, a second component and a layer of adhesive bonding the first and second components. The layer of adhesive includes multiple embedded fluorescing particles which emit a first spectral intensity in an unstressed condition and a second spectral intensity in a stressed condition. A bond evaluation apparatus is then employed for measuring spectral intensity.

摘要:
A method of manufacturing a composite article may include providing a plurality of fibers. At least a portion of the plurality of fibers may be substantially optically transparent. The method may further include forming the fibers with at least one base surface and a pair of side surfaces oriented in non-perpendicular relation to the base surface. The method may additionally include positioning the fibers in a layer in side-by-side relation to one another such that the side surfaces overlap one another when viewed along a direction normal to a plane of the layer. The method may also include embedding the fibers at least partially in a substantially optically transparent polymeric matrix.
