Transcrystallization of isotactic polypropylene (iPP) on different fibers (carbon fiber, glass fiber, and aramid fiber) was conducted in a temperature gradient. The Ultra‐High‐Module carbon fiber (UHMCF), the High‐Module carbon fiber, and the aramid fiber (Twaron) showed sufficient nucleation abilit...
