“…In most cases, PMC propulsion component applications are not load bearing or in the direct engine flow path. Components residing in the engine flow path must withstand erosion to retain structural integrity and ensure acceptable surface finish to maintain aerodynamic performance [4,5]. The survivability of PMC components is of major concern when long-term operational life requirements for fan and compressor sections involve exposure to sand and grit erosion.…”

Polymer Matrix Composites (PMCs) offer lightweight and frequently low cost alternatives to other materials in many applications. High temperature PMCs are currently used in limited propulsion applications replacing metals. Yet in most cases, PMC propulsion applications are not in the direct engine flow path since particulate erosion degrades PMC component performance and therefore restricts their use in gas turbine engines. This paper compares two erosion resistant coatings (SANRES and SANPRES) on PMCs that are useful for both low and high temperature propulsion applications. Collaborating over a multi-year period, researchers at NASA Glenn Research Center, AADC, and Rolls-Royce Engines have optimized these coatings in terms of adhesion, surface roughness and erosion resistance. Results are described for vigorous hot gas/particulate erosion rig and engine testing of uncoated and coated PMC fan bypass vanes from the AE 3007 regional jet gas turbine engine. Moreover, the structural durability of these coatings is described in long-term high cycle fatigue tests. Overall, both coatings performed well in all tests and will be considered for applications in both commercial and defense propulsion applications.
