Abstract
Electromagnetic radiation scanning is used to monitor the integrity of a composite laminate structure. The laminate is designed to be optically resonant at the frequency of the radiation, allowing the inconsistencies in the laminate to be detected and mapped.
Claims12
A method of fabricating a composite laminate enabling detection of inconsistencies in the composite laminate using electromagnetic radiation scanning, comprising:
- laminating a stack of at least two resin layers;
- selecting an approximate thickness of each of the at least two resin layers based on a preselected electromagnetic radiation frequency;
- and
- selecting a resin for each of the at least two resin layers that results in the laminated stack being substantially resonant at the preselected electromagnetic radiation frequency.
