Abstract

The invention discloses a carbon fiber composite material for a main rotor of a helicopter and a preparation method of the composite material. According to the preparation method, the surface of a carbon fiber plate is coated with a pre-cured product, the friction performance of carbon fibers is effectively improved, meanwhile, through preparation of graphene modified phenolic resin, the tensile strength of the whole product is effectively improved, and according to GB/T 31290-2014 measurement, the tensile strength of the carbon fiber composite material for the main rotor of the helicopter is 90-95 MPa. The invention further discloses coating equipment, the coating equipment can meet conveying and coating of the carbon fiber plates with different thicknesses through the arrangement of a lifting shell with the adjustable height; and through the design of a conveying mechanism, conveying rollers can meet the requirement for coating the carbon fiber plates while conveying the carbon fiber plates, and a plurality of conveying rollers are used for coating the carbon fiber plate for multiple times, so that the coating effect on the surface of the carbon fiber plate is good.

Description

technical field [0001] The invention relates to the technical field of carbon fiber preparation, in particular to a carbon fiber composite material for a helicopter main rotor and a preparation method thereof. Background technique [0002] Helicopter main rotors are based on increasingly lightweight designs, and carbon fiber materials will be used. The existing carbon fiber materials have insufficient tensile strength and are easily deformed. At the same time, during the preparation of carbon fiber materials, it is necessary to coat the surface with a material that reduces the coefficient of friction. The existing coating equipment is not efficient in coating carbon fiber plates, and the carbon fiber plates need to be fixed during coating. At the same time, the existing coating equipment The inner cavity is also inconvenient to clean. Contents of the invention [0003] The object of the present invention is to provide a kind of carbon fiber composite material and preparat...
