Continuous carbon fiber FDM 3D printing forming method

Abstract

The invention discloses a continuous carbon fiber FDM 3D printing forming method which comprises the following steps that rotatable wire coils are wound with a continuous carbon fiber filament reinforcing material and a thermoplastic plastic filament base material respectively; the two wire coils are placed in a common air blast drying box for drying; a forming chamber and a printing platform of an FDM printing system and a melting cavity and a nozzle of an extruder are heated; and the continuous carbon fiber filament reinforcing material and the thermoplastic plastic filament base material are sent to the printing system according to program settings for printing forming. By using the continuous carbon fiber FDM 3D printing forming method, a complex-shaped part printed by combining with a continuous carbon fiber reinforced polymer composite has excellent high temperature resistance and chemical resistance, so that a light high-strength 3D printing carbon fiber composite part can be manufactured, and a set of process technology with reference significance is provided for the forming process aspect of high-performance complex structural parts in China.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing and fused filament molding (FDM) 3D printing carbon fiber composite materials, in particular to a continuous carbon fiber FDM 3D printing forming method. Background technique [0002] Carbon fiber is a fiber with a carbon content of more than 90% and has high strength, high specific modulus, low density, high temperature resistance, chemical corrosion resistance, low electrical resistance, high thermal conductivity, radiation resistance, and excellent damping, shock absorption and noise reduction. Materials; Thermoplastic resins have good corrosion resistance, fracture toughness, damage tolerance, and impact resistance with low density. The carbon fiber reinforced thermoplastic composite material with carbon fiber as reinforcement and thermoplastic resin as matrix has the characteristics of light weight and high strength, reducing component weight, improving component efficiency, im...
