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 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. Interactive Graphics Video Country-Specific Mortality and Growth Failure in Infancy and Yound Children and Association With Material Stature Use interactive graphics and maps to view and sort country-specific infant and early dhildhood mortality and growth failure data and their association with maternal.

The Epon type epoxy was premixed with a hardener and delivered to PBO fiber using a syringe. Some tools below are only available to our subscribers or users with an online account. In addition, the composite failure mode would be discussed.
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.

The surface free energy of PBO fiber was analyzed from the measured contact angles between each sample and five different liquid contact media, including n-hexadecane, dimethyl sulfoxide DMSOethylene glycol EGformamide and water.
KhanHassan Mahfuz and Andreas Kyriacou. Much higher voltage would create unstable discharge that resulted sparks and could damage the fiber samples.
