Fundamental research involving polybenzoxazines (BOX) is necessary to explore its substantial potential as a next generation composite 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 effects of including systematically varied ratios of POSS-functional benzoxazine monomer within a difunctional benzoxazine network. The inclusion of two select POSS moieties reduced the viscosity of benzoxazine monomers and improved the thermomechanical properties of the resulting networks. Further research will lead to a deeper understanding of how the incorporation of covalently bound inorganic particles such as POSS affects the processability, thermomechanical properties, and UV stability of resulting benzoxazine matrices.
