In the aerospace industry the demand for very strong and light components is a permanent objective. Composites have been used in manufacturing of aircraft and turbofans for decades. This is happening due to the high strength and low density of carbon fiber epoxy composites (~1.5g/cm³) in comparison with the lightest metallic alloys as magnesium alloys (~1.8g/cm³). Although in our days technology of carbon fiber epoxy composites reached a top level through manufacturing of fan blades for or ultra-high bypass turbofans, there is a room for improvement for important reduction of average density of components made of composites. This paper shows that using a bionic technology imitating the bird's bone structure is possible for manufacturing of very light fan blades, fan vanes or fan housings having average densities smaller by several times than the compact composite materials. This technology can lead to manufacturing of very light turbofans or propfans which are the preferred propulsion systems for present aircraft. [ABSTRACT FROM AUTHOR] |
