全复合材料垂直尾翼是我国将碳纤维复合材料用于产品主要构件的首次尝试。全复合材料垂直尾翼由碳/环氧蒙皮、长桁、肋和梁组成,它的采用可以使垂尾减轻结构重量15%以上。这种材料的采用将使产品的性能得到一定的改善。 碳纤维复合材料具有可设计性,为大展弦比的机翼、整体机身及高推重比发动机的零件设计提供了可能性。但复合材料的各向异性给设计和制造工艺带来了许多麻烦。大型碳纤维复合材料门形梁的制造涉及到模具、制造工艺、变形等许多问题,必须在分析的基础上,用实验的方法,逐一确定
Full composite vertical tail is our first attempt to use carbon fiber composite material as the main component of the product. The full composite vertical tail consists of carbon / epoxy skin, stringers, ribs and beams, and its use allows the tail to reduce the structural weight by more than 15%. The use of this material will improve the performance of the product to some extent. Carbon fiber composites are engineered to provide the possibility of designing parts with large aspect ratios, integral airframes and high thrust-to-weight ratio engines. However, the anisotropy of the composite material brings a lot of trouble to the design and manufacturing process. Large-scale carbon fiber composite door beam manufacturing involves many problems, such as mold, manufacturing process, deformation, etc., must be determined on the basis of analysis, experimentally, one by one
