Brittle fracture of products
Fenómeno del problema
The product has extremely low elongation, showing brittle fracture instead of ductile yielding
Análisis de la causa
A component of the blend undergoes severe degradation during processing; phase inversion causes the matrix to lose continuity (forming a discontinuous structure); inorganic filler content is too high
Solución
Reduce processing temperature to within the safe window; adjust component proportions to ensure matrix continuity (>50%); appropriately reduce inorganic filler content to below 30%
Conclusión clave
Brittle fracture reflects the loss of the material's bulk toughness; degradation and phase morphology need to be investigated
