The surface appeared to be still uniform. No vendors are listed for this material. Trending Tags View More. The surface displayed some scars from the electrostatic treatment effects also discharge treatment. Shibboleth is an d337975 management service that provides single sign-on protected resources. Mechanics of Solids, Structures and Fluids: In addition, some unidirectional PBO fiber reinforced epoxy model composites were prepared from fiber strands. The distance between the discharge electrode and the samples was about 1.

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.
All you need to read in the other general jounals BMJ ; In this paper, the effects of surface treatment on the modification of PBO fiber and its composite materials have been investigated using electrostatic discharge under atmospheric pressure.

No chemical discharge was involved.
ASME proceedings, Volume The fiber surface morphology was examined by scanning electron microscopy. The tensile strength was then calculated from the ultimate load divided by the cross-sectional area. Users viewing this material also viewed the following: Much higher voltage would create unstable discharge that resulted sparks and could damage the fiber samples.

The effects of electrostatic discharge modification on the interfacial adhesion properties between PBO fiber and epoxy matrix were studied by microbond pull-out tests.
The degree of surface modification increased with the applied discharge voltage. Neat LDPE filaments were also extruded as control samples. If your institution uses Shibboleth authentication, please contact your site administrator to receive your user name and password.
