Embodiment 1

[0038] Step 1, the production of prepreg:

[0039] Such as figure 1 As shown, the carbon fiber cloth roll 01 is placed on the unwinding roller 11, and the unwinding roller 11 is rotatably arranged. Unwinding roller 11 rotates and carbon fiber cloth 02 can be released. The end of the carbon fiber cloth 02 is wound on the take-up roller 14 . The winding roller 14 is rotatably provided. The winding roll 14 rotates to wind the carbon fiber cloth 02 into rolls. A resin tank 12 , a resin curing device 13 , and a plurality of rollers 15 are arranged between the unwinding roller 11 and the winding roller 14 . The resin tank 12 is used to hold the resin; the resin curing device 13 is used to cure the resin impregnated with the fiber cloth; the multiple rollers 15 are used to support the fiber cloth 02 . Pulled by the winding roller 14, the fiber cloth 02 enters the resin tank 12 to be impregnated with resin in sequence, and then passes through the resin curing device 13 to cure th...

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that after the fiber cloth is impregnated with resin, before the resin is cured or during the resin curing process, the prepreg is punched by molding equipment to make it into the required shape, and then processed by the resin curing equipment. Finally, the corrugated sheet of the desired shape is formed.

[0055] Such as Figure 7 As shown, the fiber cloth 05 is released from the unwinding frame 21 with the fiber cloth 05, and the heated thermosetting resin (without solvent) is placed in the heating resin tank 22, and the released glass fiber cloth 05 is put into the heating resin The thermosetting resin is soaked in the tank, and then the fiber cloth soaked with the thermosetting resin is directly sent into the heating and softening oven 23, and the forming mold 24 is molded in the heating and softening oven 23 to form a corrugated sheet 06 of a specific shape. A cutting device 25 is provided at the exit of ...

Abstract

The invention provides a manufacturing method for a honeycomb structure made of a composite material. The manufacturing method comprises the following steps of: step 1, soaking fiber cloth with a resin material to prepare prepreg; step 2, performing mould pressing on the prepreg obtained in step 1 to form corrugated sheets with needed shapes; and step 3, stacking and jointing the corrugated sheets obtained in step 2 to form the honeycomb structure made of the composite material. The invention further provides equipment used for manufacturing the honeycomb structure made of the composite material. According to the manufacturing method for the honeycomb structure made of the composite material and the equipment used for manufacturing the honeycomb structure made of the composite material, the fiber cloth is sequentially soaked with resin and cured by the equipment, the resin adopts thermosetting resin or thermoplastic resin, viscidity of the resin can be reduced by a heating mode, and the resin is changed into a flowable state and is conveniently soaked onto the fiber cloth. In a production process, a solvent does not need to dilute, so that the pollution problem due to absence of the solvent is avoided, and therefore, the production process is environmentally friendly.

Description

technical field [0001] The invention relates to a method for manufacturing a composite material honeycomb structure and equipment for manufacturing a composite material honeycomb structure. Background technique [0002] The traditional aramid fiber honeycomb manufacturing process is to first pulp the fibers and then make paper sheets, and then bond the paper sheets to form a block structure. This block structure is stretched to form a honeycomb structure. Then soak in phenolic or other liquid resin, take it out and put it into an oven to cure and shape. Phenolic or other resins generally have high viscosity at room temperature. In order to reduce the viscosity of the resin, solvents are usually added to the resin. These solvents are usually volatile, and the environmental protection of the entire manufacturing process is poor. Contents of the invention [0003] The object of the present invention is to provide a method for manufacturing a composite material honeycomb str...
