Abstract
The utility model provides a carbon fibre composite pantograph fairing. The carbon fibre composite pantograph fairing is of a hollow box structure. The fairing is made of composite material which uses thermosetting resin as a matrix and glass fibre and carbon fibre as a reinforcing matrix. The fairing comprises a fairing body, an installation seat and an installation hole cover plate. The fairing body is connected with the installation seat. Reinforcing ribs are arranged on the fairing body in a cementing mode. The fairing body is moulded by integral split mold vacuum infusion and the reinforcing ribs are moulded by vacuum infusion. According to the carbon fibre composite pantograph fairing, a vacuum infusion moulding method is adopted to effectively overcome the defects of bad working environment and unstable quality of a traditional manual pasting technology. Porosity is reduced and overall performance is improved. A carbon fibre and glass fibre composite plate structure is adopted to enable the fairing to be lighter by more than 25%. Light weight of a vehicle is achieved. Requirements for strength, stiffness, flame retardant and noise reduction of a train are met. A plurality of the reinforcing ribs are adopted to enhance the strength and stiffness of the fairing.
