Liquid resins used for molding composite structures are a significant source of VOC (volatile organic compounds) and HAP (hazardous air pollutant) emissions. One method of reducing styrene emissions from VE (vinyl ester) resins is to replace some or all of the styrene with fatty acid-based monomers. Fatty acid monomers are ideal candidates because they are inexpensive, have low volatilities, and promote global sustainability because they are derived from renewable resources. This patent pending technology allows for the formulation of high performance composite resins with no more than 25 weight-% styrene. These resins have low viscosities suitable for vacuum infusion methods, and have excellent polymer and composite properties. As a result, these resins are currently being demonstrated/validated for DoD use on Army tactical vehicles, including HMMWV (High Mobility Multipurpose Wheeled Vehicle) hoods, HMMWV helmet hardtops, T-38 dorsal covers, and composite rudders for the Navy.
