Glass fiber surface roughening modification method

The invention discloses a glass fiber surface roughening modification method in the field of preparation of fibers and composite materials thereof. The glass fiber surface roughening modification method comprises the following steps: S101, performing oil removal and degreasing treatment on the surfaces of reinforced fibers by adopting compatibility of a surfactant with a strong emulsification effect; s102, activating the surfaces of the fibers in combination with organic alkali; and S103, non-uniformly depositing and attaching a layer of inorganic particles on the surface of the fiber by adopting an incremental method. According to the method, the original defects left in the fiber preparation process exposed after oil removal and degreasing can be made up by adopting an incremental method, the fiber strength can be kept and improved, and the glass fiber cloth subjected to roughening treatment has a good hydrophilic interface, can be directly used for enhancing inorganic materials and can also be further coat
