Embodiment approach

[0027] Such as figure 1 As shown, the invention discloses a fiber-reinforced resin honeycomb sandwich structure composite material and a preparation method thereof, which are composed of a fiber reinforcement, a resin, and a honeycomb material; the fiber reinforcement is a continuous fiber; the resin is a thermosetting resin or Thermoplastic resin; the honeycomb core is composed of aluminum honeycomb, paper honeycomb and other porous core materials. The fiber communicates with the upper and lower fiber surfaces of the honeycomb core to enhance the shear strength of the fiber-reinforced resin honeycomb sandwich structure composite material part. figure 2 Shown is the interpenetration of the internal fibers that join the upper and lower layers of fabric together. image 3 Shown is how the fiber bundles are woven into the interior of the honeycomb when using 3D weaving. Figure 4 In the process, the fiber bundles or fiber filaments connecting the upper and lower fiber cloths s...

Abstract

The invention discloses a fiber-reinforced resin honeycomb sandwich structure composite material and a preparation process thereof. According to the fiber-reinforced resin honeycomb sandwich structurecomposite material and the preparation process thereof, the upper fiber surface and the lower fiber surface are connected together through fiber yarn or fiber bundles by utilizing 3D weaving or sewing, so that the upper fiber surface and the lower fiber surface have the integrity, and therefore the problems that in an existing fiber-reinforced resin honeycomb sandwich structure material, the shearing strength of the fiber-reinforced resin honeycomb sandwich structure is low due to the fact that fiber layers and honeycombs are not bonded firmly, the connection between fibers and the honeycombsis loosen due to aging of a glue layer, and the like can be solved; and the structure is applicable to 3D weaving, and in addition, the fiber yarn or the fiber bundles can penetrate through a laid fiber reinforcement by utilizing modes such as sewing so as to connect the upper fiber surface and the lower fiber surface; and the operability is high, and the requirement for light weight of railway vehicle is met.

Description

technical field [0001] The invention discloses a fiber-reinforced resin honeycomb sandwich structure composite material and a preparation method thereof, relates to the technology for manufacturing fiber-reinforced resin honeycomb sandwich structure composite material parts, and belongs to the field of material processing. Background technique [0002] Fiber-reinforced resin honeycomb sandwich composites have high specific strength, specific stiffness, and good corrosion resistance, fatigue resistance, impact resistance and high temperature performance. As a "lightweight material" in aerospace, track It is widely used in transportation, automobile and other industries. In recent years, fiber-reinforced resin honeycomb sandwich composite materials have attracted more and more attention from the industry, and are widely used in interior decoration materials, subway floors, and high-speed rail pantograph skateboards. However, in the traditional process, the adhesive layer visc...
