The surface displayed some scars from the electrostatic treatment effects also discharge treatment. In addition, the composite failure mode would be discussed.

Here, F is the pull-out load, D is the diameter of the fiber, and L is the embedded length. Learn about subscription d33779-75 purchase options. These samples were fractured to reveal the interfacial adhesion bonding quality by the examination using scanning f3379-75 microscopy.

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

Two different operating voltages were studied at room temperature and atmospheric pressure: Each monofilament sample was mounted across a cardboard sample frame using a room temperature curing adhesive according to ASTM D However, when the applied discharge voltage was above 20 kV, the treatment process could have seriously damaged the fiber structure integrity.

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.

The cured epoxy was then debonded in shear from PBO fiber by the jaws of a microvice. Much higher voltage would create unstable discharge that resulted sparks and could damage the fiber samples.

Citing articles are presented as examples only. Neat LDPE filaments were also extruded as control samples.

The surface morphology of PBO fiber both before and after the electrostatic asfm treatment was examined by scanning electron microscopy. No chemical discharge was involved.

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.

The corresponding change in fiber tensile strength was measured by MTS tensile testing machine using a s3379-75 sample frame. The microbond specimens were pulled by MTS tensile testing machine at room temperature at a crosshead speed of 0. 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 asm pressure.

All you need to read in the other general jounals BMJ ; It seemed that a thin layer of oxidized substance has been deposited on the surface.
