本发明属于水下航行器救生筏系统用复合材料舱口盖板技术领域,尤其涉及高正浮力特性轻质高刚度可释放功能型复合材料可拆板。包括纤维增强复合材料蒙皮,所述纤维增强复合材料蒙皮为玻璃钢复合材料,玻璃钢复合材料采用手糊成型工艺或真空成型工艺;还包括由纤维增强复合材料蒙皮包覆的功能芯材;所述功能芯材包括依次由环氧胶或者高强树脂粘结的第一芯材层、第二芯材层、第三芯材层;且为吸声芯材、反声型PVC泡沫芯材或者透声型浮力芯材中的任意两种或者三种,至少一个为吸声芯材。本发明可用于水下航行器救生球阀系统的盖板的设计与制造,具有轻质,高刚度,耐腐蚀,正浮力,隐身性好的优点。

    The invention especially relates to a lightweight high-rigidity detachable plate having the characteristic of high positive buoyancy and capable of releasing a functional composite, belonging to the technical field of composite hatch cover plate for a life raft system of an underwater vehicle. The lightweight high-rigidity detachable plate comprises: a fiber reinforced composite skin, which is a glass fiber reinforced plastic composite material prepared by using a hand lay-up molding process or a vacuum molding process; and a functional core material, which is coated with the fiber reinforcedcomposite skin and comprises a first core material layer, a second core material layer and a third core material layer, wherein the three core layers are sequentially bonded by epoxy glue or high-strength resin and are any two or three selected from the group consisting of a sound absorption core material, a sound reflection type PVC foam core material and a sound transmission type buoyancy core material, and at least one of the three core layers is the sound absorption core material. The plate of the invention can be used for designing and manufacturing of a cover plate of a lifesaving ball valve system of an underwater vehicle, and has the advantages of light weight, high rigidity, corrosion resistance, positive buoyancy and good invisibility.
