The invention provides an airplane sound insulation interior structure. The airplane sound insulation interior structure comprises a front prepreg (1), an internal prepreg (5), a honeycomb core (3) and a back prepreg (6), wherein the front prepreg (1) wraps the front face of the honeycomb core (3); the back surface of the honeycomb core (3) is coated with an internal prepreg (5); the back prepreg(6) covers the internal prepreg (5), and a closed air cavity (4) exists between the back prepreg (6) and the internal prepreg (5). According to the embodiment of the invention, the air cavity can be increased on the premise of not increasing the weight of the interior structure, so that the sound insulation of the interior structure is increased.
本发明提出了一种飞机隔声内饰结构,包括:正面预浸料(1)、内部预浸料(5)、蜂窝芯(3)、背面预浸料(6),其中:蜂窝芯(3)的正面包覆有正面预浸料(1);蜂窝芯(3)的背面包覆有内部预浸料(5);背面预浸料(6)覆在内部预浸料(5)上,且背面预浸料(6)与内部预浸料(5)之间存在密闭的空气腔(4)。本发明实施例可以在不增加内饰结构重量的前提下增加空气腔从而增加内饰结构的隔声量。
