Nanomodified Carbon/Carbon Composites for Intermediate Temperature
Autor: null P., Winzek Jr., C. U. Pittman, L. A. Pilato, J. H. Koo
An improved Carbon/Carbon Composite (CCC) with enhanced thermo-oxidative resistant performance at intermediate temperatures (371 to 650 C) is being developed. A nanophase is introduced into the CCC prior to cure for improved and maintained mechanical

Ionic polyesters of fairly low molecular weights were prepared by melt phase polytransesterification of 1,1′-bis(carbethoxy)cobalticinium hexafluorophosphate (1a) and diols such as 1,10-decanediol and 1,4-bis(hydroxymethyl)benzene. Attempts to prep

Autor: C. U. Pittman, C. F. Cook, J. N. Helbert, Juey H. Lai
Publikováno v: Journal of Vacuum Science and Technology. 16:1992-1995
The positive electron beam resist exposure characteristics of poly (methacrylonitrile) (PMCN), poly(methyl α‐chloroacrylate) (PMCA), and two MCA/MCN copolymers have been obtained using conventional techniques. The 1:1 MCA/MCN copolymer is found to
