Reinforced Ceramic Composites Fabricated From High-Char Yield Polymers

Butler T., Dyatkin B., Deese S.M., Laskoski M., U.S. Naval Research Lab, US

Advancements in high-speed propulsion systems have spurred demand for materials which can withstand the harsh conditions necessitated by this hypersonic travel. Ultra-high temperature ceramics (UHTCs) such as transition metal borides, nitrides, and carbides melt at [...]

Fire Resistant, 2nd Generation Resorcinol, PEEK™-Like Phthalonitrile Composites For Advanced Applications

Laskoski M., Keller T.M., Naval Research Laboratory, US

A new oligomeric 2nd generation resorcinol, PEEK™-like phthalonitrile resin has been developed via a cost-effective methods and is being transitioned to an industrial scale. The phthalonitrile monomer used to prepare composite components exhibits viscosities much [...]

Novel Structure, Properties, and Synthesis of Refractory Carbides

Dyatkin B., Laskoski M., Rock B.Y., Qadri S., Kolel-Veetil M., Keller T.M., Gamache R.M., U.S. Naval Research Laboratory, US

Ultra-high temperature ceramics (UHTCs) and refractory carbides with high hardness and oxidation resistance demonstrate significant promise in armor and hypersonic engine applications. However, to date, they have been too brittle and expensive to widely implement [...]
