复合材料压力容器缺陷无损检测成为目前的研究热点。基于太赫兹技术（透射式 THz-TDS 系统和BWO成像系统）在室温下对玻璃纤维样品进行无损检测，获得了分层缺陷样品在0.2～1.8 THz范围内的折射率谱和吸收谱、夹杂金属和热损伤缺陷样品的成像数据。结果表明，太赫兹技术对玻璃纤维分层缺陷、夹杂金属和热损伤缺陷检测效果明显，适用于局部检测对整体性能的判断。

Defect nondestructive test of composite pressure vessel has become a hot research field at present. The glass fiber winding reinforced composite material was detected nondestructively at room temperature by the THz technology (transmission THz-TDS system and BWO imaging system). Measurement of the sample gained the absorption coefficient and refractive index of delamination defect from 0.2THz to 1.8THz and imaging data including metal and thermal damage. The results show that THz technology has obvious defect inspection effect on the samples of glass fiber lamination, including metal and thermal damage. The method can be applied to determine the overall performance of the local inspection.
