Abstract

The invention discloses a grid cover structure for an aircraft and a preparation method thereof. The grid cover structure comprises: an inner skin; an outer skin; Ribs; the grille cover structure also includes; several box-shaped parts located in the grooves formed by adjacent longitudinal ribs and inner skin, and the longitudinal ribs formed between the adjacent box-shaped parts Several vertical ribs. The technical solution of the present invention is composed of inner skin + grid interlayer + outer skin to realize the light weight and high rigidity of the grid cover structure, and has higher structural performance; the technical solution of the present invention adopts The co-curing molding process method realizes the integrated manufacturing of the grid cover structure.

Description

technical field [0001] The invention relates to the field of aircraft grille cover structure. More specifically, it relates to a grid cover structure for an aircraft and a preparation method thereof. Background technique [0002] Advanced composite materials have been widely used in aviation, aerospace, machinery, biology, medicine, sports and other fields in recent years due to their advantages such as high specific strength, high specific stiffness, good damping characteristics, long fatigue life, and structural design. The use of reinforced structure is one of the effective forms to improve the bearing capacity and stiffness of laminated panels. Among them, the grille cover structure is a special reinforced structure, which is famous in China for its strong designability and various excellent performances. The field of composite materials has received more and more attention, and has been identified as one of the three candidate manufacturing technologies (reinforced str...
