Internal strain sensing in carbon fibre composites via digital volume correlation and in situ synchrotron computed tomography

Internal strain sensing in carbon fibre composites via digital volume correlation and in situ synchrotron computed tomography
Internal strain sensing in carbon fibre composites via digital volume correlation and in situ synchrotron computed tomography
Digital Volume Correlation (DVC) is a powerful non-intrusive technique capable of volumetric full-field strain mapping of internal structures via displacement tracking. This study, a combination of DVC and in situ Synchrotron Radiation Computed Tomography (SRCT), introduces Silicon Dioxide (SiO2) particles into carbon fibre-reinforced polymers to extend the utilisation of DVC technique to more industrially relevant materials, where detailed sequences of fibre breaks and their accumulation can be identified down to the individual fibre level. The DVC analysis with strain mapping explores the process of strain redistribution longitudinally from fibre breaks that occur under quasi-static tensile loading for various load levels. It is shown that the newly developed material not only exhibits a comparable level of DVC performance to the previous study using BaTiO3 particles, but also attains improved particle distribution with reduced agglomeration. The scale/extent of strain disturbances around individual fibre breaks is compared for multiple sites, suggesting reasonable consistency and confidence in mapping ineffective lengths

Abstract

Digital Volume Correlation (DVC) is a powerful non-intrusive technique capable of volumetric full-field strain mapping of internal structures via displacement tracking. This study, a combination of DVC and in situ Synchrotron Radiation Computed Tomography (SRCT), introduces Silicon Dioxide (SiO2) particles into carbon fibre-reinforced polymers to extend the utilisation of DVC technique to more industrially relevant materials, where detailed sequences of fibre breaks and their accumulation can be identified down to the individual fibre level. The DVC analysis with strain mapping explores the process of strain redistribution longitudinally from fibre breaks that occur under quasi-static tensile loading for various load levels. It is shown that the newly developed material not only exhibits a comparable level of DVC performance to the previous study using BaTiO3 particles, but also attains improved particle distribution with reduced agglomeration. The scale/extent of strain disturbances around individual fibre breaks is compared for multiple sites, suggesting reasonable consistency and confidence in mapping ineffective lengths
