Applications of infrared synchrotron radiation to microanalysis of advanced composite systems
- Northrop-Grumman Corp., Bethpage, NY (United States); and others
The utility of characterizing both polymer and ceramic matrix composites, using the enhanced sensitivity provided by an infrared microscope integrated with a synchrotron light source, is investigated. It is shown that by substitution of the conventional infrared globar source in the microscope with high brightness IR synchrotron radiation, an increase in spectral sensitivity for both microtransmission and microreflectance can be obtained over significantly reduced sampling (aperture) areas. The improved microreflectance capability is found to considerably simplify the characterization of structural composites by eliminating the difficult microtome sectioning typically required for IR microanalysis over small (< 10 x 10 micron) sample areas. Application of the technique to thermo-oxidative stability studies of polyimide / carbon fiber composite and silicon carboxide glass (Blackglas) / Nextel fiber ceramic matrix composite systems is presented.
