| Résumé : |
High quality, clean, and well-preserved hides are paramount for competitiveness in both domestic and export markets. Currently, hides are visually inspected and ranked for quality and sale price, which is not reliable when hair is present on the hides. Advanced technologies are needed to nondestructively and accurately characterize the quality of hides and enable one to predict the mechanical properties of leather. Research was carried out to develop airborne ultrasonic (AU) methods to nondestructively characterize the quality of hides that are useful for predicting the mechanical properties of leather. The developed nondestructive method is based on measuring the AU waves transmitted through the hide samples. We performed a systematic study and used a statistical experimental design to establish the relationship between key test parameters and responding AU quantities, thereby establishing proper AU testing methods for hides. Moreover, observations showed AU parameters derived from the distributions of Time of Flight (TOFd) and the amplitude of transmitted waves (AMPd) have a strong correlation with the mechanical properties of leather. This study demonstrated that the tensile strength, stiffness, elongation, and toughness of leather could be nondestructively predicted by the physical quantities obtained from AU testing of hides. |
