PAN solvent residue affecting carbonization
Fenómeno do problema
Residual solvent in PAN precursor volatilizes during carbonization, causing pores
Análise das causas
Insufficient water washing after coagulation; incomplete solvent volatilization during drying
Solução
Increase the number of water washing stages and temperature (stepwise heating water washing); extend drying time and increase temperature; test residual liquid content <0.1%
Conclusão principal
Solvent residue is an important source of carbon fiber defects
