FRS Composites for Advanced Gas Turbine Engine Components.

Abstract

Continued property characterization and fabrication process development of fiber reinforced superalloy (FRS) composites is described. The current investigations included determination of impact toughness, low cycle fatigue properties and thermal fatigue behavior of angle plied specimens in the W-1ThO2/FeCrAlY system. Additionally, process feasibility studies were performed in the areas of monotape fabrication, secondary bonding and hollow simulated airfoil fabrication. The feasibility of using the Pre-consolidated monotape FRS blade fabrication process was demonstrated. (Author)
