Abstract

A sailplane wing design is being developed that extensively utilizes advanced composite material (graphite/aramid/epoxy). A cellular cross-section has been designed leading to the realization of an integral ribless wing box. The lower panel uses a hybrid graphite/aramid/epoxy material because of the impact resistance of aramid fibers; the upper panel uses graphite/epoxy material because of the proven better properties in compression. A small panel has been manufactured and tested under uniaxial compression.
