dc.description.abstract | Single fiber fragmentation test is extensively employed to characterize the fiber-matrix interface in composites. A
novel technique for evaluating fracture toughness and friction coefficient at the fiber-matrix interface in an epoxy
sample containing a single glass fiber is proposed. Using experimental measurements of the average fragment and
debond lengths, Boundary Element (BE) models of the portion of sample corresponding to the average fiber fragment
are created for increasing values of the applied strain. From the solution of the BE models, energy release rate (ERR)
during crack propagation is evaluated using a Fracture Mechanics based approach which accounts for fiber-matrix
interfacial friction. The calculated evolution of the ERR has a reasonably linear dependency on the applied strain,
with a decreasing slope for increasing values of the interfacial friction coefficient. Since debond growth is stable,
ERR should equal the interfacial fracture toughness during debond propagation. Consequently, interfacial friction
coefficient and fracture toughness can be simultaneously determined by parametrically varying the friction coefficient
until a null slope is obtained in the linear fit of the numerical solution of the ERR as a function of the applied strain.
The applicability of the proposed technique is demonstrated with experimental results taken from the literature. | es |
