During the period August 1 through September 30, experimental work has continued on the selection and evaluation of binder materials, on fabrication techniques, and on the carbonizing process. Apparatus has been acquired and is being standardized for differential thermal analysis of binder materials and for measurement of dynamic (sonic) modulus. This report extends the previous general discussion of graphite technology to the fabrication of the green body and its subsequent carbonization. Experimental data are reported on cold-pressing fabrication and on the survey and evaluation of binder materials. On the basis of these data it is concluded that cold-pressing cannot produce high green densities unless a vacuum is applied or a liquid phase is present; since some of the synthetic binders are thermosetting and inelastic, these may be required. Several binder materials have been found to have coke residue values comparable to that of coal tar pitch. These include a phenolic molding compound, a furfuryl alcohol polymer, polyacrylonitrile, and a butyl phenyl phenolic. It is presently believed that Resin C, phenyl-benzaldehyde, and perhaps a purified rosin will also be suitable for further d pitch and a phenolic molding compound was used.
