Title: An Analysis of the Fiber-Fiber Interactions Using the Fragmentation Test and Optical Coherence Tomography
Published: October 01, 2002
Abstract: Multi-fiber model composites are being used to conduct fundamental studies into the nucleation of failure in fibrous composites. Current results have revealed that the nucleation of critical flaws in unidirectional fibrous composites may rely on the time-dependent redistribution of stress by the viscoelastic matrix. Although their role in flaw nucleation is not clearly understood, shear deformation bands have been detected between fiber breaks. Furthermore, residual curing stresses and other interfacial phenomena have been detected in the matrix by optical coherence tomography.
