The corresponding tensile strength properties of the fiber samples were analyzed by MTS tensile testing machine at room temperature.

The surface free energy was quantified using a dynamic contact angle analysis system. The surface displayed some scars from the electrostatic treatment effects also discharge treatment.

The Epon type epoxy was premixed with a hardener and delivered to PBO fiber using a syringe. It replaces the multiple user names and passwords necessary to access subscription-based content d3379-775 a single user name and password that can be entered once per session. In addition, differential scanning calorimetry DSC and X-ray diffraction XRD studies were also conducted to measure changes in thermal and crystalline behavior. Milled SIGRAFIL C is excellent for making materials electrically conductive such as powders, dry mixtures, adhesives, floorings, aqueous adhesive systems and all aqueous mixing processes.

The PBO fiber samples were cleaned and dried before being used in the ast discharge treatment study. The surface appeared to be still uniform. You do not have access to this content.

The cured epoxy was then debonded in shear from PBO fiber by the jaws of a microvice. Mechanics of Solids, Structures and Fluids: Please contact us at webmaster matweb.

Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as well as raw conversions to equivalent units. These samples were fractured to reveal the interfacial adhesion bonding quality by the examination using scanning electron microscopy. 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.

In addition, some unidirectional PBO fiber reinforced epoxy model composites were prepared from fiber aastm.

No chemical discharge was involved. Subscribe to Premium Services Searches: Much higher voltage would create unstable discharge that resulted sparks and could damage the fiber samples. The surface morphology of the treated PBO fibers has been examined by scanning electron microscopy and is shown in Figures 1.

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. ASME proceedings, Volume The effects of electrostatic discharge modification on the interfacial adhesion properties between PBO fiber and epoxy matrix were studied by microbond pull-out tests.

We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. Questions or comments about MatWeb? The distance between the discharge electrode and the samples was about 1.

In addition, the interfacial adhesion properties of the PBO fiber reinforced epoxy composites asmt studied by microbond pull-out tests. CNTs were functionalized with OH functional groups using chemical treatment. It operates independently of a user’s location or IP address.
