Improving the mechanical properties of fluorine rubber via carbon fiber reinforcement

摘要

Composites were prepared with carbon fiber used as the reinforcement. The influence of carbon fiber content and coupling agents on the mechanical properties of the fluorine rubber was studied. Infrared Spectroscopy (IR) showed that C-Si-O bonds were generated in the composites. These improved the compatibility between carbon fiber and fluorine rubber. Scanning Electron Microscopy (SEM) showed that the carbon fiber, treated with KH550, was aligned within the rubber with no obvious sections or pores, indicating a good interphase combination between them. Optimal mechanical properties of the composites were obtained when fluorine rubber had 12 parts per hundred rubber (phr) of chopped carbon fiber.
