10 CompositesWorld DESIGN & TESTING SEPTEMBER 2017 an updated design to pass to the user's CAD software (such as CATIA), updated model properties to pass to the global loads model, and stress reports. Safer, lighter — and manufacturable e attraction of lighter aircraft, and the fuel savings that result, of course, are the major reasons why OEMs are increasingly turning to composites, but this obviously must go hand in hand with meeting all safety criteria. Our design and analysis software, for example, not only builds a positive margin of safety into every load-case run, but it also optimizes the composite design for the minimum weight that meets all applicable failure criteria with positive margins. Typical weight savings can run between 20% and 40% — and this also provides a marked reduction in material costs for the aircraft manufacturer. As product development moves from the design stage to the manufacturing phase, digital tools can continue to play an impor- tant role. For example, laminate designs can be automatically incorporated into composite layup simulations in CAD. In prepa- ration for this hand off, HyperSizer identifies the optimized ply schedules for a part, then sequences these further to account for layup producibility requirements. e ply schedules are then passed to the CAD software for ply staggering and generation of part drawings. FIG. 2 Detailed stress reports, generated in HyperSizer (in this case, for a fuselage section), contain all skin and stiffener dimensions, margins- of-safety and analysis details.
