中文摘要：

设计了一种五层夹芯多层阻尼薄膜嵌入的复合材料仪表板结构,并采用多次热压罐固化成型工艺来制作该大阻尼高刚度复合材料仪表板。它们分别是：上、下蒙皮和中心层的制作,上、下蒙皮和中心层与泡沫塑料的粘接与紧固件的预埋,孔的修正及仪表板的包边加工。通过成形质量检验和加载试验,验证了成形工艺的可行性和合理性。

英文摘要：

A new instrument panel with five-layer PMI（poly methacry limide foam） sandwiches composites structure and multilayer damping was designed in detail. In order to fabricate this large damping and high stiffness composites panel, the novel manufacturing technology of this panel was presented by curing forming in autoclave for several times. The process includes producing upper and lower skins and the middle layer, bonding upper and lower skins and the middle layer as well as PMI and embedding the screw-mounting sleeve, the correction of hole and finishing the packaged of edgeprocess. The forming quality inspection and load test verify the validity of this manufacturing technology.
