X-ray Micro-Computed Tomography and Deep Learning Segmentation of Progressive Damage in Hierarchical Nanoengineered Carbon Fiber Composites
… plies, fiber fracture, fiber bundle microbuckling, and fiber/matrix interfacial debonding. Two emerging solutions aiming to suppress or delay such mechanisms toward enhanced strength and stiffness are considered in this dissertation: (i) aligned carbon nanotube (A-CNT) interlaminar …

Compressive response of notched composite-honeycomb sandwich panels
… cross-sections indicated that individual fiber microbuckling led to out-of-plane warp tow kinking. The LDZ wake was characterized by kinking in all warp tows and transverse tow splitting. Strain gages were used to measure the in situ damage zone tractions as the LDZ propagated across the width …

Study of PECVD Films Containing Flourine and Carbon and Diamond Like Carbon Films for Ultra Low Dielectric Constant Interlayer Dielectric Applications
… using high FRRs exhibited both macro and microbuckling to a larger degree and extent. Film integrity was preserved by annealing the Fluorocarbon component or by providing a DLC base coat.

Stress rupture of unidirectional polymer matrix composites in bending at elevated temperatures
A new method for stress-rupture experiments in bending has been developed and used to characterize unidirectional polymer matrix composites. The method. which makes use of very simple fixtures, led to coherent results. These results have been modeled using the large deflection of buckled bars …
