Abstract:
The fracture mechanism of fluoroplastic bladders used at oxidizer path was analyzed after mechanics qualification environment testing. The anti-crack performance of fluoroplastic is studied and discussed in terms of melt index, hexafluoropropene content and quenching process. The results indicate that the material with high strength and anti-crack performance can be produced by adjusting the parameters of melt index, hexafluoropropene content and quenching process, and can meet the application requirements of fluoroplastic bladders.
