Characterization of Polyurethane at Multiple Scales for Erosion Mechanisms Under Sand Particle ImpactBy Nirmal Sigamani, Zoubeida Ounaies, Ramesh Talreja
Abstract: Thin polyurethane layers have been widely used as erosion-resistant coatings on helicopter rotor blades such as UH-60 Black Hawk and Eurocopter SA 315. Published research has mainly focused on empirical studies that relate the mechanical properties such as rebound resilience and hardness of polyurethane to solid particle erosion resistance. However, polyurethane possesses phase mixing at multiple scales and thus sand particle erosion resistance depends also on the microstructure and the …
