Forming of advanced composite materials
… material forming are examined. First, the fiber deformation of aligned fiber composites formed to double curvature parts is analyzed. Aligned fiber composite lay-ups were formed over hemispherical tools and the fiber deformation was mapped. The data were intended to support the model which …

Fabrication of aligned nanofiber yarns, mats and isolation of single nanofiber in electrospinning
… of submicron and nanometer scale polymeric fibers. In spite of technological advances in electrospinning, creating a highly aligned fiber structure is a tough target to be achieved because of the chaotic motion of the electrospinning jet. In this study, two different techniques have been …

The interfacial shear stress failure of flawed fiber composites
… expresses the expected length of discontinuous fiber segments in a uniaxially aligned fiber reinforced composite. The strength of elemental volumes of fiber, used in this derivation are inferred from 1ength versus strength tests.on individual fibers. The fibers are assumed to have statistically …

Cancer Protrusions on a Tightrope - Suspended Fiber Platform Reveals Protrusion Dynamics Independent of Cell Migration
… Here, we present a suspended and aligned fiber platform capable of high spatio-temporal imaging of protrusions capable of sensing fiber curvature contrasts independent of cell migration. By varying the diameter of suspended fibers, we are able to maintain cell migration along low …

Biophysical Influence of Nanofiber Networks to Direct Pericyte Aggregation into Spheroids
… assemble into 3D structures. We used suspended fiber networks to demonstrate a new way to form and spatially pattern spheroids comprised of human pericytes. We show that fiber architecture (aligned vs. crosshatched), diameter (200, 500, and 800 nm), and contractility influence spheroids in their …

Microenvironmental Modulation of Breast Cancer Stem Cells Through Biological Matrix
… of electrospun fibrous scaffolds with random and aligned fiber orientations. Breast cancer cells were cultured on these fibrous scaffolds for 3-5 days. The cells showed elongated spindle-like morphology in the aligned fibers whereas kept mostly flat stellar shape in the random fibers. Gene …

A Method for Winding Advanced Composites of Unconventional Shapes using Continuous and Aligned Fibers
… achieved this by winding continuous, uncut, and aligned fibers. This process is called Lotus Filament Winding.</p>
