Elastomeric Phases for Toughening Air Force High-Temperature Polymers

Authors: C. Kumudine; J. K. Premachandra; J. E. Mark; M. R. Unroe; F. E. Arnold; CINCINNATI UNIV OH DEPT OF CHEMISTRY
Abstract:
A number of high-temperature polymers of interest and importance to the U.S. Air Force have a degree of brittleness that limits their utilization. This brittleness was reduced, and a number of other physical properties were improved, by the in-situ introduction of dispersed elastomeric phases. This was done in a modification of the sol-gel approach previously used to modify other properties by the introduction of much harder ceramic-like phases.
