Key concepts
Scholarcy highlights
- The development and nature of the transcystalline-like superstructure produced by pulling the glass fiber from the isothermal crystallizing isotactic polypropylene melt was studied thermooptically
- In the vicinity of the pulled GF α row-nuclei form which induce selective β-nucleation resulting in β-cylindrites
- The presence of α row-nuclei was evidenced by selective melting of the β-phase having lower melting temperature than the α
- Because of the above change in the crystal modification this phenomenon can not be termed by transcrystallinity
- It was suggested that the observed αβ-bifurcation may be related with epitaxial growth
- Paper presented on the conference “Microphenomena in Advanced Composites”
- Direct evidence of row-nucleated cylindritic crystallization in glass fiber-reinforced polypropylene composites
