Microstructural observations and flexural property datasets are provided for aluminum alloy matrix syntactic foam core sandwich composites. The tests are conducted in three-point bending configuration. The data supplied includes methods used for conducting microscopy and mechanical testing. Raw load-displacement data, which is used to plot stress-strain graphs, obtained during the flexural test is also included. Images from a DSLR camera are stitched together to form a detailed failure sequencing video. Failure of specimens is captured in sequential images using a digital camera. These images are stitched together to develop a video for visualization of failure mechanisms. Calculations are also included for a theoretical model that is used to estimate the flexural properties of the syntactic foam core sandwich.
提供了铝合金基复合泡沫夹芯三明治复合材料的微观结构观察结果和弯曲性能数据集。测试采用三点弯曲配置进行。提供的数据包括用于进行显微镜检查和机械测试的方法。还包括在弯曲试验期间获得的用于绘制应力-应变图的原始载荷-位移数据。来自数码单反相机的图像拼接在一起，形成详细的失效顺序视频。使用数码相机在连续图像中捕捉试样的失效情况。这些图像拼接在一起，制作出一个用于可视化失效机制的视频。还包括一个用于估计复合泡沫夹芯三明治弯曲性能的理论模型的计算。
