Abstract
A manufacturing method for a carbon fiber includes: performing an emulsification step that includes uniformly mixing a silicone oil composition and an emulsifier to form an oiling agent, in which the silicone oil composition includes γ-divinyltriamine propylmethyldimethoxyl silane and N-(β-aminoethyl)-γ-aminopropylmethylbimethoxy silane; performing an oiling step that includes soaking a carbon raw filament in the oiling agent, such that the oiling agent is adhered to a surface of the carbon raw filament to form a carbon fiber precursor; and performing a calcination step on the carbon fiber precursor, such that the carbon fiber is formed.
