Improved High Temperature Resistant Matrix Resins.
Abstract
This final report document describes the work performed by the TRW Electronics and Defense Sector for the National Aeronautics and Space Administration, Lewis Research Center, under Contract NAS3-23274. The technical work was performed during the period of January through December, 1982. The objective of this program was to develop organic matrix resins suitable for service at temperatures up to 644 degrees K (700 degrees F) and at air pressures up to 0.4 MPa (60 psia) for time durations of a minimum of one hundred hours. Matrix resins capable of withstanding these extreme oxidative environmental conditions would lead to increased use of polymer matrix composites in aircraft engines and provide significant weight and cost savings. In this program, six linear condensation, aromatic/heterocyclic polymers containing fluorinated and/or biphenyl linkages were synthesized. The thermo-oxidative stability of the resins was determined at 644 degrees K and compressed air pressures up to 0.4 MPa. Two formulations, both containing perfluoroisopropylidene linkages in the polymer backbone structure, exhibited potential for 644 degrees K service to meet the program objectives. Two other formulations could not be fabricated into compression molded zero defect specimens. (MM)
