Abstract:
It is the goal of the aerospace industry to minimize the weight of structural parts without compromising the structural integrity of its hardware. This can be achieved through the implementation of sound design requirements in order to eliminate the unnecessary weight associated with high localized stress areas. A second method of reducing the structural weight is to select materials that have superior mechanical properties. Recently at Boeing, more attention is given to composite materials, where high strength fibers are reinforced in polymers capable of carrying the environmental load. The 787 aircraft is an example of Boeing’s dedication and good judgment to apply composite materials where it is believed to have superior mechanical properties over materials that have been previously used such as aluminum or titanium alloys. Moreover, Boeing decided to enhance the mechanical properties of composites even further by reinforcing nanoparticles (nanofillers) in the resin for the hope of getting better ultimate and fracture toughness values. This novel approach can help Boeing to significantly reduce aircraft fuel consumption. Furthermore, the application of this technology to Boeing’s next generation aircrafts can have a profound effect on the impact of aircraft on the ozone quality and global warming.
