Interfacial debonding of single fibers in transverse tension

Conference ·
OSTI ID:89837
A micromechanical method to measure and analyze interfacial debonding of single fibers in transverse tension was developed. The damage process was observed in-situ by optical microscopy. Two glass fiber/epoxy (GF/EP) systems were studied with different fiber surface treatment. Results from calculations of the interfacial fracture toughness for Mode I and Mode II failure are presented. The theoretical analysis is based on a modification of Toya`s stress analysis of a de bonded circular inclusion, calculation of the work required to I close the crack and a mixed-mode failure criterion.
