Fundamental research involving polybenzoxazines is necessary to explore its substantial potential as a next generation material for aerospace and Low earth Orbit (LEO) applications. In recent years the inclusion of well-defined inorganic structures such as polyhedral oligomeric silsesquioxane (POSS) in systems like polyimides has been shown to improve the mechanical properties and reduce the color of the resulting matrices. This research investigated the effect of including systematically varied ratios of POSS-functional benzoxazine monomer within a difunctional benzoxazine network. Our research showed that inclusion of POSS influenced the thermomechanical properties of the resulting networks. This research will lead to an understanding of how incorporation of covalently bound inorganic particles such as POSS affects the processability, thermomechanical properties, and UV stability of resulting benzoxazine matrices.
