The invention relates to the technical field of composite materials, in particular to a composite material for lightweight rail transit bridges and a molding process thereof. The invention obtains a composite by uniformly mixing modified carbon fiber, heat-resistant agent and photoinitiator and subjecting the mixture to ultraviolet light irradiation; uniformly mixes polyvinyl chloride resin, acrylonitrile-butadiene-styrene copolymer, the composite, plasticizer, antioxidant, stabilizer and lubricant, and performs internal mixing in an internal mixer at 165-175°C to obtain a blend; finally, adds the blend into a twin-screw extruder for extrusion and granulation to obtain the composite material. The composite material prepared by the invention has excellent heat resistance and mechanical properties, and can effectively meet the service requirements of lightweight rail transit bridges.
