The proposed effort will utilize lithiated POSS in synergistic combination with commercial phosphates to achieve comparable processing characteristics and superior flame retardancy, smoke and toxicity to that of Derakane® 510A. The POSS-phosphate synergist package will be formulated into a Hydrex® nonhalogenated vinylester resin and superior mechanical properties (interlaminar shear strength and carbon fiber adhesion) will be demonstrated. An analysis of material and manufacturing cost is presented and will be validated during the effort.
