Development of Some Promising Approaches for the Toughening of High-Temperature Polymers
Abstract
A number of 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 the physical properties improved, by the in-situ introduction of dispersed elastomeric phases. The approach was a modification of the sol-gel technique previously used to introduce much harder ceramic-like phases into similar polymers. Specifically, precursor molecules were chosen so that their hydrolyses did not produce a ceramic such as silica, but one in which organic groups flexibilize the phases. This increases extensibility and thereby toughness, and has some additional benefits such as decrease of water absorption.
