Nanomodified Carbon/Carbon Composites for Intermediate Temperature

Abstract

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 baseline phenolic resole. Six resin/nanoparticle material systems were selected and transformed into prepregs, followed by fabrication into composites for carbonization and densification to produce CCC.
