Tensile damage evolution in unidirectional CFRP via in situ X-ray CT and digital volume correlation

Key Points

• The aim is to understand tensile damage evolution in unidirectional carbon fiber reinforced polymers (CFRP) using advanced imaging techniques.
• Utilized in situ X-ray computed tomography (CT) to monitor damage progression in CFRP over time.
• Applied digital volume correlation to analyze the strain distribution and failure mechanisms during tensile testing.
• Identified distinct stages of damage evolution in unidirectional CFRP under tensile loading; initial micro-cracking led to eventual failure.
• Quantified strain localization and its correlation with damage progression during testing.
