Honeycomb spliced multilayer foam core aircraft composite parts and method for making same |
摘要 |
Aircraft composite components having foam cores comprising at least two foam sheets joined with a sheet of honeycomb to form a foam-honeycomb-foam sandwich. The layers of sheet foam are in contact with each other and the honeycomb cells extend a substantially equal depth into and generally perpendicular to the sheet foam layers. The composite component has increased shear strength. The aircraft composite component can be made by aligning a layer of honeycomb between and generally perpendicular to two layers of sheet foam. A compressive force is applied generally perpendicular to at least one layer of sheet foam so that the honeycomb cells penetrate each of the two layers of sheet foam to a substantially equal depth so that the layers of foam contact each other to form a foam-honeycomb-foam sandwich. The foam core is surrounded by resin impregnated fibers and cured.
