Abstract

The corrugated foam core sandwich construction is used in variety of structural applications. These structures are subjected to flexural, impact, edgewise compression and shear loads. Traditional process for manufacturing of sandwich panel is not suitable for making corrugated core sandwich panel. In this work a novel methodology has been developed for construction of corrugated foam core sandwich panel. The present study focuses on the flexural behaviour of sandwich panel by varying the foam densities and corrugated cell. Two types of densities with one cell and two cells are used. The sandwich employs a Glass Reinforced Polymer (GRP) orthotropic material for both the two outer skins and the inner core web. In particular, the core is designed to have uneven topology to cooperate with GRP skins in membrane and flexural properties by adding a corrugated foam core. At first, a comparison has been performed between different density foams. Initially, 40 kg/m3 with 1 unit cell and 32 kg/m3 with 1 unit cell are compared, and then the same densities are compared with 2 cells. Among all, 40 kg/m3 with two cells shows highest flexural strength compared to the other specimens. Also, the sandwich panel with an empty core has been tested to understand the strength of the face sheet and corrugated core.

波纹玻璃增强聚合物夹层板的弯曲特性

波纹泡沫芯夹层结构用于各种结构应用。这些结构承受弯曲、冲击、边缘压缩和剪切载荷。传统的夹芯板制造工艺已不适合制作波纹芯夹芯板。在这项工作中，开发了一种新的方法来建造波纹泡沫芯夹芯板。本文研究了不同泡沫密度和波纹单元对夹芯板弯曲性能的影响。两种类型的密度，一个细胞和两个细胞被使用。三明治采用玻璃增强聚合物(GRP)正交各向异性材料，用于两个外层和内芯网。特别地，芯被设计成具有不均匀的拓扑结构，通过添加波纹泡沫芯来配合GRP外皮的膜和弯曲性能。首先，对不同密度的泡沫进行了比较。首先比较1个单元槽40 kg/m3和1个单元槽32 kg/m3，然后用2个单元槽比较相同的密度。其中，40kg /m3含两个孔的试件抗弯强度最高。此外，夹层板与一个空的核心已被测试，以了解的强度面板和波纹芯。
