Benzoxazine Materials and Composites
Benzoxazines are thermosetting polymers that offer several unique characteristics for use in composite materials, including fire resistance, chemical resistance, low moisture uptake in hot/wet environments, high glass transition temperatures, high char yields, and good dielectric performance. CTD is developing 100% benzoxazine formulations that offer high-temperature performance, and that can be used with either VARTM or prepreg fabrication methods. Ongoing work at CTD involves the production of wear-resistant bearings, as well as structural composites that take advantage of the unique performance characteristics of these materials.
