This invention relates to polymer synthesis processes and carbon fiber composite preparation techniques, specifically concerning a chopped carbon fiber-reinforced, blend-modified phenolic polyarylethernitrile resin composite material and its preparation method. Its key technical features are as follows: a resin with excellent processing fluidity is synthesized as an additive to reduce the melt viscosity of the matrix resin; a sizing agent resin with good film-forming properties and containing polar groups is synthesized for surface modification of carbon fibers; the modified carbon fibers and matrix resin are melt-blended via a twin-screw extruder to prepare the composite material. The invention provides a sizing-modified short-cut carbon fiber reinforced blend modified phenolic polyarylethernitrile resin composite material and its preparation method. This confers excellent processing fluidity to the matrix resin, enhances fiber-resin wetting, and simultaneously strengthens the fiber-resin interface strength through the sizing agent, resulting in significantly improved mechanical properties. It can be widely applied in transportation vehicles, sports equipment, and other fields.
