ORNL–General Atomics partnership on ceramic matrix composites
A memorandum of understanding has been signed by Oak Ridge National Laboratory and General Atomics Electromagnetic Systems (GA-EMS) with the objective of working together on advanced ceramic matrix composite materials for applications in extreme environments. Materials that can withstand extreme temperatures, radiation, corrosion, and mechanical stress are required in aerospace, defense, energy, and other sectors.
According to the agreement, the San Diego–based GA-EMS will use resources from ORNL’s Manufacturing Demonstration Facility to develop “scalable, efficient manufacturing techniques for extreme environment materials including precursors, fibers, composites, and coatings utilized in carbon/carbon (C/C), carbon/silicon carbide (C/SiC), and SiC/SiC composite systems.”

The procedures and facilities necessary for performing endurance tests of hydrophobic catalysts have been designed.The endurance tests were carried out in real operational conditions using 2 stands with recirculation of tritiated water at constant temperature on catalyst bed. Radio-induced alterations were studied by pH determination and fluoride ion presence in samples of tritiated water. In the polymeric hydrophobic support the radio-induced modifications have been analyzed by FTIR ATR spectrometry and by determination of extractable fractions. The swelling degree has been also estimated. 6 different catalysts on PTFE support and 1 catalyst on copolymer styrene divinylbenzene (SDB) produced by ICIT Rm Valcea have been tested using the proposed protocols and facilities.
