Marine composite propellers are ship propellers made from fiber composites. These composites are made from materials like glass or carbon fibers and infused with a high-strength resin like epoxy or polyimide.
Attributes edit
Composite propellers can be made using a lay-up process, leading to anisotropic properties. This can create a passive adaptation of self-twisting propeller blades, which are considered more energy-efficient when compared to rigid propeller blades.[1]
Longevity edit
Composite materials may be considered an environmentally friendly option for propeller blades in some applications. While the composite blades are more resistant to corrosion and impact damage than many metal-alloy propeller blades, the water saturation and the propeller application decrease the longevity of composite propellers.[2][3][4]
