摘要

An experimental and analytical study on the structural behavior of two carbon fiber reinforced plastic composite sandwich fuselage side panels for a transport aircraft is presented. Each panel has two window cutouts and three frames and uses a distinctly different structural concept. These panels have been evaluated with internal-pressure and axial tension load loading conditions. One of the sandwich panels was tested with the middle frame removed to demonstrate the suitability of this two-frame design for supporting the prescribed biaxial loading conditions with twice the initial frame spacing. A damage tolerance study was conducted on the two-frame panel by cutting a notch in the panel that originated at the edge of a cutout and extended in the panel hoop direction through the window-belt area. This panel with a notch was tested in a combined-load condition. Both sandwich panel designs successfully satisfied all desired load requirements in the experimental part of the study, and experimental results from the two-frame panel with and without damage are fully explained by the analytical results. The results of this study suggest that there is potential for using sandwich structural concepts with greater than usual frame spacing to further reduce aircraft fuselage structural weight.
