Abstract
-
This report supplements WADD Technical Report 61-72, Volume XII, "Development of an Improved Large-Diameter Fine-Grain Graphite for Aerospace Applications", by C. W. Waters and E. L. Piper, and covers the continuation of development work on large diameter grade RVA graphite. The extension work consisted primarily of fabricating and evaluating raw materials for use as the inert filler in RVA blends, and of attempts to scale up to longer lengths of RVA graphite.
Significant properties of raw materials, as they affect the final properties of grade RVA graphite, were the total porosity and kerosene apparent density. The more porous raw materials imparted higher strength to the finished RVA graphite, whereas those of higher density contributed to higher density of the finished graphite. Long lengths of 33-inch diameter RVA graphite were difficult to process without cracking. The longest length processed successfully under this project was 45 inches.
