Glass Fibre low elongation at break
Fenómeno do problema
Glass Fibre product elongation at break <100%, below the 200% requirement
Análise das causas
Glass Fibre molecular weight too low, chains short, entanglement insufficient; excessive orientation, transverse elongation extremely low; excessive crosslinking limits chain slippage
Solução
1) Select high molecular weight Glass Fibre to increase entanglement density; 2) reduce orientation, lower injection speed; 3) control crosslinking degree to avoid excess
Conclusão principal
Low elongation at break is caused by low molecular weight and orientation; selecting high MW and reducing orientation are key
