Liquid rocket engines can be divided into two broad categories: those used for tactical missiles and those used for space applications. Although both types require high performance, which implies maximum operating temperature, other criteria strongly influence the choice of materials. For tactical missiles, operating times are short (seconds to minutes) and weight is critical, ceramic composites typically dominate this area because of their significant weight advantage. For space applications, operating times are long (hours to tens of hours) and performance/ erosion rate is critical. The state-of-the-art material in this field is the iridium/rhenium (Ir/Re) metallic composite developed by Ultramet and fabricated by chemical vapor deposition (CVD). This paper will discuss the processing and performance of ceramic and metal composites being developed at Ultramet to advance the state of the art for these applications.
