... prior to fracture. Pristine and Non-Pristine Fibers Fibers without flaws are called pristine or ‘flawless’. Fibers with flaws are called non- pristine. Routinely manufactured fibers ... the fracture initiating flaws (Mecholsky, 1994). It is not possible to use fractography for high- strength fibers because, upon fracture, high-strength fibers disintegrate into powder. When...
