point本文通过对于薄蜂窝复合材料夹芯结构的平压全过程试验研究,得到了夹芯结构破坏过程图以及载荷-位移曲线,进一步通过分析得到不同载荷下夹芯结构的状态。复合材料夹芯结构自产生以来,因其优良的性能受到航空航天行业内的认可,已成为一种十分重要的结构材料。夹芯结构由于其特点,在飞机结构高度大的位置(例如蒙皮壁板)取代加筋结构应用能较大程度的减轻重量,在飞机结构高度小的位置采用夹芯结构亦可起到明显的减重作用。
In this paper, through the experimental study on the whole process of the flat pressing process of the thin honeycomb composite sandwich structure, the failure process of the sandwich structure and the load-displacement curve are obtained, and the state of the sandwich structure under different loads is obtained. Since its production, the composite sandwich structure has been recognized by the aerospace industry for its excellent performance and has become a very important structural material. Due to its characteristics, the sandwich structure can reduce the weight to a great extent by replacing the stiffened structure with a large aircraft structure (such as a skin panel), and the sandwich structure can also be obviously used where the height of the aircraft structure is small Weight loss.
