Abstract
Efforts to replace metals with composites in shipboard applications have emphasized the use of brominated vinyl esters as fire-retardant polymers. Despite their relatively low cost and ease of fabrication, such halogenated polymers produce toxic and potentially carcinogenic gases; their compatibility with carbon fibers is also less than desirable. There is thus a need for environmentally friendly and affordable polymers that offer desired fire resistance, processability, structural performance and compatibility with carbon fibers. This challenge is addressed in the project by developing a modified epoxy chemistry which employs the organic-inorganic hybridization principle. Chemical integration of phosphorus- and silicon-based compounds into selected epoxy systems yielded a single, inherently flame-retardant polymer structure with a desired balance of fire, smoke and toxicity behavior, compatibility with the resin-infusion approach to room-temperature processing of composites, thermo-mechanical performance, bonding characteristics, and economics. The Phase II project will optimize this modified epoxy chemistry, and will undertake laboratory investigations and scale-up efforts towards qualification of the new polymer composite for use in shipboard structures. The proposed project will be implemented in a base (Phase II) and two option steps, and will be guided by the experience gained in successful qualification of composites for use in Naval surface combatants.
