However, when the applied discharge voltage was above 20 kV, the treatment process could have seriously damaged the fiber structure integrity.
The surface appeared to be still uniform. The microbond specimens were pulled by MTS tensile testing machine at room temperature at a crosshead speed of 0.

CNTs were functionalized with OH functional groups using chemical treatment. 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.
Surface modification of PBO fiber by electrostatic discharge for composites. Two different operating voltages were studied at room temperature and atmospheric pressure: It replaces the multiple user names and passwords necessary to access subscription-based content with a single user name and password that can be entered once per session.

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.
All you need to read in the other general jounals BMJ ; In addition, differential scanning calorimetry DSC and X-ray diffraction XRD studies were also conducted to measure changes in thermal and sstm behavior. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. The cured epoxy was then debonded in shear from PBO fiber by the jaws of a microvice. The degree of surface modification increased with the applied discharge voltage.
Here, F is the pull-out load, D is the diameter of the fiber, and L is the embedded length. The surface displayed some scars from the electrostatic treatment effects also discharge d33797-5.
PBO Fiber, PBO Composite Materials, – Fibre2Fashion – 2
The Epon type epoxy was premixed with a hardener and delivered to PBO fiber using a syringe. It seemed that a thin layer of oxidized substance has been deposited on the surface.

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

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

Much higher voltage would create unstable discharge asstm resulted sparks and could damage the fiber samples.
