复合材料参数在超声检测中的影响

Impact of composite materials parameter in ultrasonic detection

针对十六层碳纤维增强型复合材料进行超声波探伤的研究,提出一种判定复合材料分层缺陷位置的简便方法,经实验验证可行,并得出结论:碳纤维复合材料的弹性模量对超声波的声速与入射范围有重要影响,这将直接决定缺陷位置判定的准确性。

Aiming at carbon fibrerein forced composite material, investigating the ultrasonic non-destructive testing. Advanced a calculation to determinating position of the defect location and concluded ： MOE affected significantly the ultrasonic sound speed and incidence angle.
