Insights into Moisture Uptake and Processability from New Cyanate Ester Monomer and Blend Studies

Abstract

Two major limiting factors in the use of cyanate ester resins for high-temperature aerospace applications are durability in hot/wet environments and the trade-off between obtainable glass transition temperatures and ease of processing. In order to understand how the molecular-level structure of cyanate ester resins relates to both of these issues, studies of cyanate ester monomers with novel chemical structures as well as studies of monomer blends are underway at the Air Force Research Laboratory. In particular, new tricyanate ester monomers containing mixtures of stereochemical isomers have exhibited significantly improved processability, while studies of ternary monomer blends provide a unique means of testing various mechanisms of moisture uptake.
