Curved crease honeycombs with tailorable stiffness and dynamic properties

Issues with pleat walled honeycombs are solved by replacing polygonal creases with curved creases. As with a conventional straight-walled honeycomb, these strips can be combined into a space-filling honeycomb structure. The benefits of these curved creases are threefold. First, the stress concentrations mentioned above with pleat-walled honeycombs are mitigated. The stress due to finite material thickness is spread more evenly over the crease line, instead of being concentrated at a point, as with pleat walled honeycombs. As a result, the maximal value observed is lower and the adverse effects are reduced. Second, the curved creases also serve to give better control over material properties, and third, the curved crease honeycombs do not require any of the horizontally-running creases. The curves are typically mathematical curves that can be computed algebraically or by solving a differential equation. 1.

Impregnation process method for improving compression strength of water-soluble resin honeycomb core material

本发明属于复合材料制造技术领域，涉及一种提高水溶性树脂蜂窝芯材压缩强度的浸胶工艺方法，该工艺方法可用于芳纶纸蜂窝芯材的制备，提高蜂窝芯材的压缩强度。本发明将浸渍树脂更换为水溶性酚醛树脂，减少了溶剂挥发对环境的污染，同时因水溶性酚醛树脂的游离酚含量远低于传统醇溶性酚醛树脂，也减少了浸胶过程中游离酚对操作人员的危害。本发明在浸胶过程中利用水溶性酚醛树脂自身的特点，采用特殊的浸胶工艺方法，对树脂在蜂窝壁上的分布情况进行了有效控制，使树脂集中在蜂窝芯材六边形角附近后形成胶柱，有效的提高了蜂窝芯材的压缩强度，与同等密度芳纶纸蜂窝芯材相比，采用本发明所述方法制备的蜂窝芯材可使其稳定型压缩强度提高30％以上。

Forming method of low-cost multi-embedded honeycomb sandwich composite material product

本发明公开了一种低成本多预埋蜂窝夹芯复合材料产品的成型方法，在产品总体要求厚度不变的前提下，由原来单层蜂窝结构改成双层蜂窝结构，可以实现预埋孔的分段切割，具有更灵活的结构设计性，可极大的提高预埋组件与蜂窝芯材之间的结构连接强度。同时还在蜂窝芯材单面先粘接一层碳纤维预浸料蒙皮，进而提高蜂窝芯材的刚性，采用人工或者成本低的普通自动裁床都能实现对预埋孔的精确切割加工，而由于解决了蜂窝芯材切割的问题，通过碳纤维、泡沫等材料的加强筋预制体埋到蜂窝板中，将结构强度要求高的预埋单元件在蜂窝板内部连接起来，形成力学传递途径，分散应力，解决预埋件应力集中问题，从而提高各个关联预埋单元件的结构力学强度。
