Image correlation spectroscopy (ICS) is known to be a useful tool for the evaluation of fiber width in the extracellular matrix. Here we evaluate a more general from of ICS fit parameters for fiber networks and arrive at a means of quantifying the fiber density, pore size and length which facilitates the characterization of the extracellular matrix. A simulation package was made to create image...

A new Euler model is proposed to predict fiber orientation distribution at high Reynolds number in a dilute planar contraction. The model mainly accounts for the evolution of mean velocity and turbulence-induced rotational diffusion coefficient along the contraction. It is shown that the new model, as the function of local turbulent dissipation rate, fiber length, and fluid viscosity, can refle...

This paper reports microfluidic chip based wet spinning of biodegradable polymers with simple mechanism, and study of cell orientation dependence with fiber size. Biodegradable polymer PLGA fiber was produced by microfluidic chip based spinning device. By controlling feed rate of core polymer and sheath coagulating solutions, we got various PLGA fiber diameter from 10 to 242 μm. L929 mouse fibr...

In this paper we present a constitutive relation for predicting the rheology of short glass fibers suspended in a polymeric matrix. The performance of the model is assessed through its ability to predict the steady-state and transient shear rheology as well as qualitatively predict the fiber orientation distribution of a short glass fiber (0.5 mm, L/D < 30) filled polypropylene. In this approac...

Ab&act The structural performance of medium density fiberboard (MDF) is attributable to three primary variables which are: physical and mechanical properties of individual wood fibers; fiber-to-fiber stress transfer; and fiber orientation. These origins of fiber properties and stress transfer can be traced to the fiber generation method wherein fiber orientation is associated with mat formation...

This paper presents a 2D coupled Hele-Shaw flow approximation for predicting the flow-induced orientation of injection molded composite parts within a commercial concentration range. For a highly concentrated short glass fiber PBT suspension, the impact of inter-particle interactions and the orientation at the gate is investigated for a center-gated disk using a time-delayed orientation evoluti...

Magnetic resonance (MR) diffusion tensor imaging (DTI) can resolve the white matter fiber orientation within a voxel provided that the fibers are strongly aligned. However, a given voxel may contain a distribution of fiber orientations due to, for example, intravoxel fiber crossing. The present study sought to test whether a geodesic, high b-value diffusion gradient sampling scheme could resolv...
