Mechanical Property Characterization of P-5Ag Silver-Filled Carbon
Abstract
Silver-filled carbon ring material P-5Ag, produced by Morgan AM&T, Inc., has been used in cryogenic applications. For example, it was used to fabricate carbon ring seals for the Atlas RL 10 engine. However, the mechanical properties of this material, i.e., tensile strength and modulus, shear strength and modulus, as well as fracture toughness, have not been well characterized, particularly at the liquid-nitrogen temperature. A test series was conducted to characterize both the room-temperature and the cryogenic-temperature mechanical properties for silver-filled carbon material P-5Ag. The P-5Ag carbon material was procured from Morgan AM&T, Inc. The types of tests in this series included tensile strength, tensile modulus, shear strength, shear modulus, flexure strength and modulus, mode I fracture toughness, and coefficients of thermal expansion (CTE). However, because of the limited number of tests in each category, highly reliable engineering allowables cannot be established.
