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.
Astm d 75 pdf – Lucidity
The PBO fiber samples were cleaned and dried before being used in the electrostatic discharge treatment study. Citing articles are presented as examples only. 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 3d379-75 chemical treatment. MatWeb is intended for personal, non-commercial use.
The surface morphology of PBO fiber both before and after the electrostatic discharge treatment was examined by scanning electron microscopy.

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 d3379-5 of surface modification increased with the applied discharge voltage. It seemed that a thin layer of oxidized substance has been deposited on the surface.
Surface modification of Qstm fiber by electrostatic discharge for composites. The cured epoxy was then debonded in shear from PBO fiber by the jaws of a microvice.

In addition, some unidirectional PBO fiber reinforced epoxy model composites were prepared from fiber strands. Results and discussion 3. In this paper, the effects asrm surface treatment on the modification of PBO fiber and its composite materials have been investigated using electrostatic discharge under atmospheric pressure.
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 tensile strength was then calculated from the ultimate load divided by the cross-sectional area. Related Content Customize your page view by dragging and repositioning the boxes below. However, when the applied discharge voltage was above 20 kV, the treatment process could have seriously damaged the fiber structure integrity.

In addition, differential scanning calorimetry DSC and X-ray diffraction XRD studies were also conducted to measure changes in thermal and crystalline behavior. Here, F is the pull-out load, D is the diameter of the fiber, and L f3379-75 the embedded length.
Each monofilament sample was mounted across a cardboard sample frame using a room temperature curing adhesive according to Ashm D 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 surface appeared to be still uniform.
