Glass Fibre insufficient toughness, brittle fracture
Fenómeno do problema
Glass Fibre product elongation at break <50%, brittle fracture without yield
Análise das causas
Glass Fibre molecular weight too low, toughness foundation insufficient; excessive crosslinking loses toughness; coarse crystallization increases brittleness
Solução
1) Select high molecular weight Glass Fibre to improve toughness; 2) control crosslinking degree to avoid excess; 3) nucleating agent refines crystallization to improve toughness
Conclusão principal
Insufficient toughness is caused by low molecular weight and coarse crystallization; selecting high MW is key
