| Abstract: | Porosity is important to the morphology and microstructure of PAN precursor,which is closely related to the properties of PAN-based carbon fiber.In the paper,the causes and evolutions of porosity and properties in PAN precursor are analyzed and discussed in the spinning process.Meanwhile,several ways be taken to characterize the configuration of porosity in PAN precursor are introduced. |
