Description

一种超强吸收能量的轻质复合材料结构及应用
技术领域
本发明涉及一种复合材料结构，具体的涉及一种超强吸收能量的轻质复合材料结构及应用。
背景技术
现有水路桥墩的保护一般是通过在桥墩周围加钢柱或钢筋混凝土柱来抵挡从船只来的冲撞，但是这些保护柱不可能很粗，因为那样会影响船只的航行，所以这些保护住对桥墩的保护是有限的，而对于公路桥墩进行这样的保护也不现实，因为保护柱会减少车流量，更重要的是对行车的安全有较大的影响，增加车祸的可能性。因此，急需一种能把桥墩包起来的结构，即使被撞击也会吸收撞击能量，使桥墩不受损伤，更不至于发生桥墩的撞断事故，避免造成了更为严重的后果。
发明内容
为了能够吸收因撞击产生的能量，避免因撞击桥墩发生更为严重的事故，更为安全的保护桥墩，本发明提供了一种超强吸收能量的轻质复合材料结构，其特征在于：从内层到外层依次包括第一材料内层、第一缓冲层、第二金属内层、第二缓冲层、第三金属内层、第三缓冲层和金属外层，所述第一缓冲层包括设有垂直于第一材料内层的数个支撑管及填充在数个支撑管管壁间隙之间的PU泡沫，所述第二缓冲层包括PVC泡沫或者铝泡沫，所述第三缓冲层包括设有垂直于第三金属内层的数个支撑管及填充在数个支撑管管壁间隙之间的PU泡沫。
进一步的，所述支撑管为玻璃纤维管、碳纤维管、竹管或者金属管的一种或者组合。
进一步的，所述金属外层的厚度为3-5mm，所述第二金属内层和第三金属内层的厚度为1-2mm，所述PU泡沫的厚度为150-250mm。
进一步的，所述第二缓冲层还包括微小空心球和/或纳米土粉。
进一步的，所述支撑管的厚度：直径比为0.05-0.15。
进一步的，所述第一材料内层由不锈钢合金、玻璃纤维、碳纤维或者高密度聚氨酯泡沫制成。
一种根据权利要求1-6任一项所述的轻质复合材料结构在桥墩上的应用。
本发明的有益效果为：本发明采用非常新颖可实用的设计理念，造价低，易于现场操作，最大限度的利用材料的抗压特性，以及泡沫对支撑管变形的制约作用，本发明结构能够最大限度的发挥抗撞的优良性能，并同时减轻重量和节省材料，最大限度吸收船或车的冲撞能量，从而对桥墩起到应有的保护作用。

图2为本发明的应用示意图；
其中，第一材料内层1，第二金属内层2，第三金属内层3，金属外层4，支撑管5，PU泡沫6，第二缓冲层7，桥墩8，轻质复合材料结构9。
具体实施方式
以下结合附图对本发明作进一步地说明：本发明提供了一种超强吸收能量的轻质复合材料结构，其特征在于：从内层到外层依次包括第一材料内层1、第一缓冲层、第二金属内层2、第二缓冲层7、第三金属内层3、第三缓冲层和金属外层4，所述第一缓冲层包括设有垂直于第一材料内层1的数个支撑管5及填充在数个支撑管5管壁间隙之间的PU泡沫6，所述第二缓冲层7包括PVC泡沫或者铝泡沫，所述第三缓冲层包括设有垂直于第三金属内层3的数个支撑管5及填充在数个支撑管5管壁间隙之间的PU泡沫6，所述支撑管5为玻璃纤维管，所述金属外层4的厚度为3-5mm，所述第二金属内层2和第三金属内层3的厚度为1-2mm，所述PU泡沫6的厚度为150-250mm，所述第二缓冲层还包括微小空心球，所述支撑管5的厚度：直径比为0.05-0.15，所述第一材料内层1由不锈钢合金制成。
实际上，本结构中的支撑管可以是为玻璃纤维管、碳纤维管、竹管或者金属管的一种或者它们的任何组合，第二缓冲层还可以包括微小空心球和/或纳米土粉，本结构9应用在保护桥墩8上，这种易于现场制作的超强吸收能量的新型轻质复合材料结构通过将支撑管嵌入PU泡沫和添加剂的混合物经适当搅拌处理而成，其性能取决于如何制作PU液体以及如何添加添加剂并搅拌、夹层结构的设计、使用的纳米土粉和空心球、预制的温度和压力以及时间等，而对于对PU的密度、支撑管的嵌入模式以及和第一材料内层的搭配，通过计算机辅助工程，使这种新型轻质夹层结构达到对桥墩的最佳保护作用。
