Neat LDPE filaments were also extruded as control samples. In this paper, the effects of surface treatment on v3379-75 modification of PBO fiber and its composite materials have been investigated using electrostatic discharge under atmospheric pressure.
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.

Here, F is the pull-out load, D is the diameter of the fiber, astn L is the embedded length. The surface free energy of PBO fiber was analyzed from the measured contact angles between each sample wstm five different liquid contact media, including n-hexadecane, dimethyl sulfoxide DMSOethylene glycol EGformamide and water.
The microbond specimens were pulled by MTS tensile testing machine at room temperature at a crosshead speed of 0. 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.
CNTs were functionalized with OH functional groups using chemical treatment. Mechanics of Solids, Structures and Fluids: 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.
The distance between the discharge electrode and the samples was about 1. The surface morphology of the treated PBO fibers has been examined by scanning electron microscopy and is shown in Figures 1.

Results and discussion 3. It operates independently of a user’s location or IP address. No chemical discharge was involved. The corresponding change in fiber tensile strength was measured by MTS tensile testing machine using a cardboard sample frame.
There was a problem providing the content you requested
The surface free energy was quantified using a dynamic contact angle analysis system. However, when the applied discharge voltage was above 20 kV, the treatment process could have seriously damaged the fiber structure integrity. You do not have access to this content.
In addition, the interfacial adhesion properties of the PBO fiber reinforced epoxy composites were studied by microbond pull-out tests. The surface displayed some scars from the electrostatic treatment effects also discharge treatment.
