Investigation of Characteristic Microstructures of Adhesive Interface in Wood/Bamboo Composite Material by Synchrotron Radiation X-Ray Phase Contrast Microscopy
摘要
第三代同步辐射光源X射线相位衬度显微CT能获得样品内部结构的边缘增强图像, 实现对低Z材料成像。 利用上海同步辐射光源X射线相衬显微成像技术, 实现了竹木复合材料中EPI和MUF胶合界面和胶黏剂渗透特征的无损探测, 并基于这些特征分析了几种不同加工工艺对胶黏剂在木材和竹材中渗透的影响。 该技术为人造板工艺解剖学研究提供了一种重要无损检测手段。
Abstract
Third-generation synchrotron radiation X-ray phase-contrast microscopy(XPCM)can be used for obtaining image with edge enhancement, and achieve the high contrast imaging of low-Z materials with the spatial coherence peculiarity of X-rays. In the present paper, the characteristic microstructures of adhesive at the interface and their penetration in wood/bamboo composite material were investigated systematically by XPCM at Shanghai Synchrotron Radiation Facility (SSRF). And the effect of several processing techniques was analyzed for the adhesive penetration in wood/bamboo materials. The results show that the synchrotron radiation XPCM is expected to be one of the important precision detection methods for wood-based panels.
