چکیده انگلیسی
High-modulus aramid fiber was exposed to energetic (5 eV) atomic oxygen, which simulates the space environment in low Earth orbit. It was found that Young’s modulus and tensile strength decreased significantly due to the atomic oxygen exposures. X-ray photoelectron spectroscopy showed that the decomposition of amid group occured at the exposed surfaces. Scanning electron microscopy revealed that the diameter of the fiber was not influenced so much by the attack of atomic oxygen, but the exposed fiber became an extremely rough surface. The change in mechanical properties has been explained by the formation of surface texture that is characteristic to the high-energy atomic oxygen collisions.
