Composite Hemisphere Feasibility Study
Abstract
The feasibility of applying slip casting technology to the fabrication of a complex rounded carbon matrix composite structure having a controlled metal carbide content has been investigated. The slip casting technology is based on the use of certain controlled particle size formulations; i.e., resin, carbon/graphite powders, and reinforcing fiber to fabricate a high strength carbon matrix composite structure. Formulations were prepared in which certain metal carbide powders, TiC, TaC, and ZrC, were incorporated into the slip formulation replacing selected fractions of the carbon/graphite powders. Conditions were established for the compression molding and carbonization of Z- loaded carbon hemispheres of approximately 4 in. O.D. and 100 mils wall thickness. Two different Z-layered structures (50 mils each) were fabricated into a single (100 mil) hemisphere. These carbon hemispheres showed little distortion and surface cracks after heat treatment up to 1400 C.
