Insufficient Toughness and Brittle Fracture of CMC
Fenómeno do problema
Elongation at break of CMC products <50%, brittle fracture without yielding
Análise das causas
CMC molecular weight is low and toughness foundation is insufficient; excessive crosslinking loses toughness; coarse crystallization increases brittleness
Solução
1)Select high-molecular-weight CMC to improve toughness; 2)Control crosslinking degree to avoid excess; 3)Nucleating agent to refine crystallization and improve toughness
Conclusão principal
Insufficient toughness is caused by low molecular weight and coarse crystallization; selecting high MW is the key
