Description

一种具有夹心结构的复合板及其制造方法
技术领域
本发明涉及一种复合板，具体来讲是一种具有夹心结的构复合板及其制造方法。
背景技术
蛋壳型夹心结构一般是用来吸收冲击能量的，因而通常用铝合金、碳纤维、玻璃纤维、纸板或其它轻质材料制成，蛋壳型夹心结构做成的面板表层则用强度较高的材料做成来抗坚硬物体的撞击，蛋壳型夹心结构的性能与夹心的结构形态和材料选择，有至关重要的联系，现有蛋壳型夹心结构一般由铝合金或硬塑料做成，其单位质量的吸能性难以达到最佳状态，做成的面板，也很难达到较好的抗冲击效果。
发明内容
为解决上述提到的问题，本发明提供一种具有夹心结的构复合板及其制造方法，为实现该目的，本发明的技术方案如下：
一种具有夹心结构的复合板，所述的复合板包括有上面板、下面板以及位于上面板和下面之间的夹心层，所述的夹心层包括有一个以上的以拓扑结构排列的凹型支撑件和缓冲物，所述的缓冲物设于上面板和凹型支撑件以及凹型支撑件和下面板之间。
进一步的，所述的凹型支撑件包括有侧支撑环面以及和所述的侧支撑环面相接的底面，侧支撑环面的底部开口小于顶部开口。
进一步的，所述的侧支撑环面由4个依次相接的曲面和4条筋条组成，所述的曲面和曲面之间通过筋条相连接。
进一步的，所述的缓冲物为PU泡沫。
进一步的，PU泡沫的密度为40-100Kg/m3。
进一步的，所述的上面板和下面板的由10-20层碳纤维或玻璃纤维构成，所述的碳纤维或玻璃纤维的厚度为1-2mm。
进一步的，所述的夹心层的厚度为10-30mm。
进一步的，所述的支撑结构由碳纤维、玻璃纤维或金属构成，其厚度为1-2mm。
一种具有夹心结构的复合板的制备方法，所述的制备方法包括如下步骤：（1）设计和制作好模具后，将碳纤维或玻璃纤维于模具内热压出支撑结构，其中压力为1.5-2.5MPa，温度200-250 ℃；（2）将上面板和下面板粘接在支撑结构的上方和下方；（3）向上面板和下面板之间注入缓冲物 PU泡沫。即制成了具有夹心结构的复合板。
本发明的有益效果在于，这种新型轻质拓扑夹心结构制备的面板，最大限度地利用材料的抗压特性，以及碳纤维或玻璃纤维增强板壳与泡沫的相互作用，使用碳纤维或玻璃纤维增强层板制备面板材料，使本发明达到了最佳能量吸收-重量比以及刚度。
