最近几年对纤维增强的复合材料有许多检测方法。本文只扼要地叙述通常应用于生产检验的方法。射线照相常规的低压X射线透视设备能测碳纤维增强叠层结构的单个大气孔、密集小孔、杂质、与射束平行的裂纹、零件内部蜂窝芯损伤和各种类型的残余物,也能检测脱粘,但测不出纤维体积含量。用钚238放射源可对硼/环氧复合材料测定纤维体积含量,因而可能应用于碳的检测。最新的成就是将显微荧光检查同电视处理技术相结合。这种仪器正被生产检验所采用。曾采用X射线不易穿透的渗透剂来改善不连续部
There have been many tests on fiber-reinforced composites in recent years. This article only briefly describes the methods commonly used in production testing. Radiography Conventional low-pressure X-ray fluoroscopy equipment can detect individual macrocarbons, dense pores, impurities, cracks in parallel with the beam, internal honeycomb core damage and various types of residue in carbon fiber reinforced laminated structures, Debonding, but can not measure the fiber volume content. Plutonium 238 radioactive sources can be measured on the boron / epoxy composite fiber volume content, which may be applied to the detection of carbon. The latest achievement is the combination of microfluidics and television processing. This equipment is being used for inspection. The use of penetrating X-rays penetrant to improve the discontinuity
