Modeling of Microstructures and Stiffness of Injection Molded Long Glass Fiber Reinforced Thermoplastics
… of the use of injection molded discontinuous fiber-reinforced thermoplastics. During the intensive injection molding process, severe fiber breakage arises in the plasticating stage leading to a broad fiber length distribution. Fiber orientation distribution (FOD) is another highly anisotropic …

Dynamics of Rigid Fibers in a Planar Converging Channel
The influence of turbulence on the orientation state of a dilute suspension of stiff fibers at high Reynolds number in a planar contraction is investigated. High speed imaging and LDV techniques are used to quantify fiber orientation distribution and turbulent characteristics. A nearly homogenous, …

Mechanical properties of bio-absorbable materials
… Poly-e-caprolactone (PCL), matrices with Carbon fibers (AS4), Nylon fibers and PLLA fibers. Fiber coating effects have also been investigated, with compliant polymers (1%, 50% and 100% of matrix properties) and with hydroxyapatite (HA). Unidirectional, continuous fiber plies, and …

Extension of the Method of Ellipses to Determining the Orientation of Long, Semi-flexible Fibers in Model 2- and 3-dimensional Geometries
The use of fiber-reinforced polymer composites formed via injection molding is of increasing interest due to their superior mechanical properties as compared to those of the polymer matrix alone. These mechanical properties, however, are strongly dependent on the fiber length and orientation …

Imaging 3D tissue fiber organization using optical polarization tractography
… three-dimensional (3D), depth-resolved images of fiber organization in tissue. To validate OPT's accuracy in measuring fiber orientation, a comprehensive histology comparison study was conducted using heart tissues which are known to have a depth-dependent fiber orientation change. A systematic …

IMPACT OF HEAT TREATMENT AND OXIDATION OF C/C COMPOSITES ON MICROSTRUCTURE AND PHYSICAL PROPERTIES
… dependent on various parameters: microstructure, fiber type, fiber orientation distribution, fiber/matrix interfacial bond, heat treatment, and oxidation. The present study in dissertation provides an insight into the impact of heat treatment, and oxidation on microstructure, mechanical and …

Electrospun nanofibers with tunable electrical conductivity
… is a convenient method to produce nanofibers with controlled diameters on the order of tens to hundreds of nanometers. The resulting nonwoven fiber mats are lightweight, highly porous, and have high specific surface areas around 1 to 100 m2/g. Combined with the high electrical …
