PMI泡沫的太赫兹无损检测研究
首发时间:2019-03-22
摘要:聚甲基丙烯酰亚胺(Polyme thacry limide, PMI)泡沫是一种先进的泡沫芯材,其具有诸多的优秀特性,在多个高科技领域的重要部件都得到了广泛的应用。然而,在生产、服役过程中,泡沫芯材结构难免会出现各种缺陷。太赫兹时域光谱(THz-TDS)技术是利用太赫兹脉冲电磁波来反映物质性质的一种新型光谱技术,太赫兹辐射对泡沫材料具有半透明性,因而其在该类材料的检测当中具有巨大潜力。本文以PMI泡沫为检测对象,组建了太赫兹时域光谱系统,以太赫兹技术在PMI泡沫无损探测中的效果。本文的研究可以为先进泡沫芯材的无损检测提供一种新的方法。

Nondestructive Testing of PMI Foam Based on Terahertz Imaging Technology
Abstract:Polyme thacry limide (PMI) foam is an advanced foam core. It has many excellent properties and has been widely used in many high-tech fields. However, in the course of production and service, there will inevitably be various defects in the structure of foam core. Terahertz time-domain spectroscopy (THz-TDS) is a new type of spectral technology which reflects terahertz pulse waves to reflect the properties of materials. Terahertz radiation has a translucency for foam materials, so it has great potential in the detection of such materials. In this paper, a terahertz time-domain spectroscopy system is built with PMI foam as the testing object, and the effect of terahertz technology in PMI foam nondestructive detection is established. The research in this paper can provide a new method for nondestructive testing of advanced foam core.
