Heterogeneous dissipative composite structures

Design and Operational Diagnostics of Marine Propellers Made of Polymer Materials

“…Another factor is the durability of the propeller, as a viable propeller made from isotropic material must have enough strength to withstand the operating load [3]. Tests of composite materials [3][4][5]adding up analysis of fatigue damage mechanisms by combining different techniques: optical microscopic and X-ray microtomography observations, temperature field measurement by infrared camera, and acoustic emission monitoring (AE subject to thermal conditioning and operation in water indicate that they have high strength properties, and are strong enough to withstand the operational loads on marine propellers. The third factor is the service life of the propeller when submerged in water.…”
