Abstract

The invention discloses a nondestructive detection method for a rubber composite material based on terahertz time-domain spectral imaging. The nondestructive detection method comprises the following steps: performing reflective imaging on a to-be-detected rubber material through a terahertz time-domain spectral detection device to obtain a detection image; detecting the thickness of the rubber material according to the terahertz time-domain spectroscopy; and degumming and layering the rubber material for detection according to a terahertz time-domain spectroscopy. The rubber material can be subjected to nondestructive detection and analysis by using terahertz time-domain spectroscopy nondestructive detection, the thickness of the rubber material is detected and analyzed through a detectionimage, a B-scan graph and a detection waveform, and the thickness of the rubber material is accurately calculated through the refractive index and the absorptivity of the rubber material; layering positions can be qualitatively determined by analyzing and detecting a grey-scale map, a time domain oscillogram and the B-scan graph, and the layering size can be accurately judged through calculationof the refractive index.

Description

technical field [0001] The invention relates to the technical field of terahertz spectral detection, in particular to a nondestructive detection method for rubber composite materials based on terahertz time-domain spectral imaging. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and often a large molecular weight, greater than hundreds of thousands. At present, the most used rubbers on the market are Nitrile Rubber, Neoprene Rubber, and EPDM Rubber. [0003] At present, many testing methods for rubber materials are damaged, and the only non-destructive testing method is ultrasonic testing, but ultrasonic absorption of rubber materials is too large, so it can only detect sur...
