The degree of surface modification increased with the applied discharge voltage. Sign into or create your free personal account. However, when the applied discharge voltage was above 20 kV, the treatment process could have seriously damaged the fiber structure integrity.

The distance between the discharge electrode and the samples was about 1. Mechanics of Solids, Structures and Fluids: Login to see your most recently viewed materials here.

The surface morphology of the treated PBO fibers has been examined by scanning electron microscopy and is shown in Figures 1. In addition, differential scanning calorimetry DSC and X-ray diffraction XRD studies were also conducted to measure changes in thermal and crystalline behavior.

In addition, the interfacial adhesion properties of the PBO fiber reinforced epoxy composites were studied by microbond pull-out tests.

These samples were fractured to reveal the interfacial adhesion bonding quality by the examination using scanning electron microscopy.

Shibboleth is an access management service that provides single sign-on protected resources. The fiber surface morphology was examined by scanning electron microscopy. The cured epoxy was then aastm in shear from PBO fiber by the jaws of a microvice. The surface free energy was quantified using a dynamic contact angle analysis system.

The surface morphology of PBO fiber both before and after the electrostatic discharge treatment was examined by scanning electron microscopy. The corresponding change in fiber tensile strength was measured by MTS tensile testing machine using a cardboard sample frame. MatWeb is intended for personal, non-commercial use.

Here, F is the pull-out load, D is the diameter of the fiber, and L is the embedded length.
