Abstract

Benzoxazine-based resins often afford high modulus and high glass transition polymers that are desirable for creating safe and reliable thermoset parts and composites. However, benzoxazine resins have had limited widespread deployment into industry due to their high cure temperature. By blending functionalized glass substrates with the benzoxazine monomer, we hypothesize that the cure temperature of thermosetting resin can be lowered. The structure and purity of the particles, determined by NMR and FTIR, will be presented. DSC studies on the stability and cure accelerating properties of blends composed of functionalized glass substrates and benzoxazine monomer will be determined and compared against blends composed of un-functionalized glass substrates and a benzoxazine monomer. TGA studies for thermal stability of silica particles will also be discussed. The extent of functionalization of the silica will be studied via TGA and XPS. The application of this science may be used as an alternative to the current phenolic resins used in the aerospace industry.
