Abstract

The invention discloses a manufacturing process for a carbon fiber composite forming membrane disk. The manufacturing process comprises the steps that a prepreg is slit into a prepreg body in a certain shape and angle; a mold is cleaned and coated with a mold releasing agent; a heating platform is used for carrying out preheating treatment on the cut prepreg body; the prepreg body is laid to forma carbon fiber composite layer in a regular shape; a vacuum membrane bag is used for carrying out sealing treatment, and vacuumizing is carried out to form negative pressure; an oven is used for heating and solidifying the carbon fiber composite layer; the cooled carbon fiber composite layer is separated from the mold; the carbon fiber composite layer is cut and polished, and a finished product ofthe carbon fiber composite forming membrane disk is obtained. The membrane disk manufactured through the method has high-content fiber, the surface is bright without bubbles, the interlayer bonding intensity achieves an effect of a compression molding process, and the requirement for carbon fiber composite product production in the fields of aerospace and navigation.

Description

Technical field: [0001] The invention relates to a manufacturing process of a carbon fiber composite material forming membrane disc, in particular to a closed mold internal pressure forming process of a prepreg carbon fiber composite material. Background technique: [0002] Resin-based carbon fiber reinforced phase composite material is lighter than metal aluminum, but its strength is higher than steel, and it has the characteristics of corrosion resistance and high modulus. With many excellent properties, carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, ultra-high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between non-metal and metal Among them, the coefficient of thermal expansion is small and anisotropic, with good corrosion resistance and good ray transparency. Good electrical and thermal conductivity, good electromagnetic shielding, etc. [0...
