The surface morphology of the treated PBO fibers d337975 been examined by scanning electron microscopy and is shown in Figures 1. The degree of surface modification increased with the applied discharge voltage.
In addition, some d379-75 PBO fiber reinforced epoxy model composites were prepared from fiber strands. The distance between the discharge electrode and the samples was about 1.
Results and discussion 3. Customize your page view by dragging and repositioning the boxes below. In addition, differential scanning calorimetry DSC and X-ray diffraction XRD studies were also conducted to measure changes in thermal and crystalline behavior.
Neat LDPE filaments were also extruded as control samples. Users viewing this material also viewed the following: Subscribe to Premium Services Searches: In d3379–75, the interfacial adhesion properties of the PBO fiber reinforced epoxy composites were studied by microbond pull-out tests. 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.

The tensile strength was then calculated from the ultimate load divided by the cross-sectional area. 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.
