碳纤维复合材料被广泛应用于军事和民用领域，全面检测其缺陷十分重要。针对

Carbon fiber composite materials are widely used in military and civilian fields, and it is very important to comprehensively detect their defects. Aiming at the fact that the existing defect detection technology cannot achieve online synchronous detection, the research on the fusion detection mechanism and detection information fusion method of laser ultrasound, speckle interference, infrared thermal image, and carbon fiber composite material defect detection based on terahertz time domain spectroscopy technology The study of the method has obtained a new method that can perform on-line synchronous non-contact non-destructive testing of complex defects in composite materials.

Carbon fiber composite materials are widely used in the military and civilian fields, it is very important to comprehensively detect their defects. For the existing defect detection technology can not achieve on-line synchronous detection, through laser ultrasound, spot interference, infrared thermal image fusion detection process and its detection information fusion method research, as well as based on tyhertz spectral technology carbon fiber composite defect detection method, to obtain a new method for on-line synchronous non-contact non-destructive detection of complex defects of composite materials.
