The distance between the discharge electrode and the samples was about 1. The surface free energy was quantified using a dynamic contact angle analysis system. Results and discussion 3.

The tensile strength was then calculated from the ultimate load divided by the cross-sectional area. The surface appeared to be still uniform.

In addition, differential scanning calorimetry DSC and X-ray diffraction XRD studies were also conducted to measure changes in thermal and crystalline behavior. 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. Surface modification of PBO fiber by electrostatic discharge for composites. Or if you don’t have an account with us yet, then click here to register.

Here, F is the pull-out d3397-75, D is the diameter of the fiber, and L is the embedded length. However, when the applied discharge voltage was above 20 kV, asm treatment process could have seriously damaged the fiber structure integrity. All you need to read in the other general jounals BMJ ; 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 surface morphology of the treated PBO fibers has been examined by scanning electron microscopy and is shown in Figures 1. It seemed that a thin layer of oxidized substance has been deposited on the surface. Each monofilament sample was mounted across a cardboard sample frame using a room temperature curing adhesive according to ASTM D In addition, some unidirectional PBO fiber reinforced epoxy model composites were prepared astn fiber strands.

In addition, the composite failure mode would be discussed. MatWeb is intended for personal, non-commercial use. Shibboleth is an access d3379-57 service that provides single sign-on protected resources.

Citing articles are presented as examples only. The cured epoxy was then debonded in shear from PBO fiber by the jaws of a microvice. In addition, the interfacial adhesion properties of the PBO fiber reinforced epoxy composites were studied by microbond pull-out tests.

The corresponding change in fiber tensile strength was measured by MTS tensile testing machine using a cardboard sample frame.

Much higher voltage would create unstable discharge that resulted sparks and could damage the fiber samples. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error.
