Evaluation of Rigid-Rod Polymeric Fibers by Post-Treatment in scC02

Abstract

Poly-p-phenelenebenzobisoxazole (PBO, commercial name ZylonTM, Toyobo Co.)is one of the rigid-rod polymers which produces fiber with excellent mechanical properties. This polymer, originally developed by the U.S. Air Force to replace metals in space and aviation applications, is currently one of the more promising materials for fibers used in personnel ballistic armors. In this study we evaluate the degradation mechanisms of PBO fibers and investigate strategies to stabilize them using supercritical CO2 as an extraction medium, a transport medium, and a polymerization medium. Various treatments and their effects are reported herein.
