Abstract

Abstract: The large hyperbolic honeycomb sandwich structure is a kind of complex structure form in composite materials, it has the charecteristics of large size and complex profile. But its mechanical bearing performance is good, light weight, and has strong resistance to deformation. Sandwich nacelles are studied, the structure characteristics and processing technology are discussed in detail. The honeycomb core is easy to shrink and hard to fix, and the assembly area requires high technical difficulties. The experimental scheme, experimental data, and engineering differences are analyzed and compared. Finally, a set of effective forming methods were obtained.

Key words: hyperbolic, honeycomb structure, nacelles, composites
