Kind Code:
A1
Abstract:
The present invention pertains to the technical field of carbon fiber modification, and relates to a method employing an aromatic fused ring molecule to modify assembly of a carbon fiber surface. The method comprises the following steps: conducting an imidization reaction of an aromatic fused ring dihydric anhydride and a diamine to obtain an aromatic fused ring imide molecule assembly liquid; immersing carbon fibers in the aromatic fused ring imide molecule assembly liquid, such that the aromatic fused ring imide molecules adhere to the carbon fibers, so as to obtain carbon fibers having a modified surface assembly. The modification method of the present invention is adopted to improve the chemical activity on the surface of carbon fibers. The present invention further provides a method for preparing a resin matrix composite material having a carbon fiber reinforced interface: after the carbon fibers having the modified assembly surface are obtained, compounding and curing the carbon fibers having the modified surface assembly and a resin, to give a resin matrix composite material having an interface reinforced by a carbon fiber assembly modified with an aromatic fused ring molecule. The interface reinforced resin matrix composite material given by the preparation method has good interfacial bonding strength and interfacial shear strength.
