Ultra-fast time-lapse synchrotron radiation CT imaging of compressive failure in unidirectional glass fibre-epoxy composite
收藏资源简介：
This series of ultra-fast X-ray computed tomography datasets were acquired on the TOMCAT beamline at the Swiss Light Source by the composite group at Henry Moseley X-ray Imaging Facility (within the Henry Royce Institute @Manchester). The experiment was designed to help understand the catastrophic failure of unidirectional fibre reinforced composites under compression, as part of Ying Wang's PhD project (Damage Mechanisms Associated with Kink-Band Formation in Unidirectional Fibre Composites) supervised by Prof. Philip J. Withers. A notched unidirectional glass fibre-epoxy composite specimen was loaded in-situ under compression in a tension/compression rig developed at INSA-Lyon. An initial scan of the composite gauge section was acquired before loading (GFRP_Initial.zip). During the in-situ loading process, the composite specimen was imaged statically at 200 N (GFRP_Static_200N.zip) and 600 N (GFRP_Static_600N.zip), after which the acquisition mode was changed to continuous streaming in order to capture the final stages immediately leading up to failure, at 876 N (GFRP_Continuous_876N.zip), 893 N (GFRP_Continuous_893N.zip), 895 N (GFRP_Continuous_895N.zip), and right after collapse (at 79 N, GFRP_Failed.zip). The CT acquisition speed attained 1 tomogram per second. The voxel size of the reconstructed CT data-sets is (1.1 μm)3.

本系列超快X射线计算机断层扫描（X-ray Computed Tomography）数据集由英国曼彻斯特大学亨利·罗伊斯研究所下属的亨利·莫塞利X射线成像课题组，在瑞士光源的TOMCAT光束线上采集完成。本实验为菲利普·J·威瑟斯教授指导的王颖博士课题（课题名称：单向纤维复合材料弯折带形成相关损伤机制）的一部分，旨在揭示单向纤维增强复合材料在压缩载荷下的灾难性失效机理。 实验采用INSA里昂开发的拉压试验装置，对带缺口的单向玻璃纤维-环氧树脂复合材料试样进行原位压缩加载。加载前，先对复合材料标距段完成首次扫描（文件：GFRP_Initial.zip）。在原位加载过程中，分别在200 N（GFRP_Static_200N.zip）与600 N载荷下对试样进行静态成像；随后将采集模式切换为连续流式采集，以捕获失效前的最终阶段，对应载荷分别为876 N（GFRP_Continuous_876N.zip）、893 N（GFRP_Continuous_893N.zip）、895 N（GFRP_Continuous_895N.zip），并在试样坍塌后即刻（79 N载荷下）完成成像（GFRP_Failed.zip）。 本数据集的CT采集速度可达每秒1幅断层图像，重建后CT数据的体素尺寸为(1.1 μm)³。 如需使用本数据集，请引用该数据集仓库的DOI（http://doi.org/10.5281/zenodo.2597497）及以下相关学术论文： 1.
