Surface modification of PBO fiber by electrostatic discharge for composites. The PBO fiber samples were cleaned and dried before being used in the electrostatic discharge treatment study. The surface morphology of PBO fiber both before and after the electrostatic discharge treatment was examined by scanning electron microscopy. In addition, the composite failure mode would be discussed.
