In the last forty years, the composite materials increased from single-digit percentages to more than 40 percentof airframe weight. Weight reductions achieved with composites reduce fuel consumption and greenhouse gasemissions. Today, single-aisle passenger jets boast from a few hundred to a few thousand pounds of compositesper airframe. And during the next decade, the production of advanced composites for airframe components isexpected to grow by more than 200 percent worldwide. Subject to many of the same performance demands thatdrive those who build aircraft primary structures, designers and manufacturers of aircraft interiors have turnedto composite materials. Interior composites are no less crucial to the operating-cost and revenue-generationdiscussion. In fact, for many commercial aircraft, the weight of composite interiors significantly exceeds theweight of composite airframe structures.Zodiac Aerospace (ZA) is manufacturing cabin interiors for the aviation industry utilizing composite paneltechnologies. Variability of composite panels caused by warping, twisting, bowing or bending observed on theas received panel or at any point during the manufacturing process can significantly increase production costs.The panel dimensional control problem increases scrap rate, inspection costs, and engineering costs whichultimately can cause delays in delivery targets to the customer.The objective of this project is to propose a solution to improve dimensional stability of composite panels foraircraft interiors. The process currently used by ZA to produce, store, manipulate and machine the panels willbe reviewed. Using advanced composite material process simulation tools, new guidelines will be developed toreduce and control dimensional stability issues during the manufacturing of aircraft interiors. Besides theeconomic benefits of an improved process, cost efficiency results in a more stable and reproducible process.

在过去四十年中，复合材料在机身重量中所占的比例从个位数增加到了 40% 以上。通过复合材料实现的减重减少了燃料消耗和温室气体排放。如今，单通道客机的每个机身使用了数百至数千磅的复合材料。未来十年，全球用于机身部件的先进复合材料产量预计将增长 200% 以上。飞机内饰设计者和制造商与制造飞机主要结构的人员一样，为了满足许多相同的性能要求，飞机内饰设计师和制造商已转向复合材料。内饰复合材料对于运营成本和创收讨论同样至关重要。事实上，对于许多商用飞机来说，复合材料内饰的重量大大超过了复合材料机身结构的重量。Zodiac Aerospace (ZA) 正在利用复合材料面板技术为航空业制造机舱内饰。在收到的面板上或在制造过程中的任何时刻观察到的复合面板的翘曲、扭曲、弓形或弯曲引起的变异会显着增加生产成本。面板尺寸控制问题增加废品率、检查成本和工程成本，最终会导致向客户交付目标的延迟。该项目的目标是提出一种解决方案，以提高飞机内饰复合面板的尺寸稳定性。 ZA 目前用于生产、存储、操作和加工面板的流程将受到审查。使用先进的复合材料工艺模拟工具，将制定新的指导方针，以减少和控制飞机内饰制造过程中的尺寸稳定性问题。除了改进工艺的经济效益之外，成本效率还可以使工艺更加稳定和可重复。
