초록

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 g...
