The major objective of this material program is to develop an improved epoxy nanocomposite for carbon fiber-reinforced polymer matrix composite (CPMC) with higher temperature performance capability, mechanical performance, damage resistance, extreme environment corrosion resistance, and improved dimensional control. We proposed that a nanophase be introduced into specific components of an epoxy resin system, prior to cure, to provide improved Tg and mechanical strength of the composites. In this study, we ...
The introduction of inorganic nanomaterials as additives into polymer systems has resulted in polymer nanostructured materials exhibiting multifunctional, high performance polymer characteristics beyond what traditional polymer composites possess. Selective thermoplastic elastomers have been used with montmorillonite organoclays, POSS(registered), carbon nanofibers to develop a flame resistant material. Thermal and flammability properties of these polymer nanocomposites will be presented.
An improved Carbon/Carbon Composite (CCC) with enhanced thermo- oxidative resistant performance at intermediate temperatures (700 to 1200 degrees F) was investigated. A nanophase was introduced into the CCC NCCC) prior to cure for improved and maintained mechanical strength by preventing oxidation of the composites. Three types of nanoparticles: chemically modified MMT clay, POSS(R), and carbon nanofiber (CNF), were used in conjunction with precursor resins such as cyanate ester (CE) and ...
