Embodiment 1

[0037] refer to Figure 5, using UG, Pro / Engineer, CAD software to establish a regular hexagon with a side length of 10mm and a honeycomb wall thickness of 0.3mm; the closed-cell honeycomb core unit is 10mm high, and the closed plane thickness is 0.3mm; the closed-cell honeycomb mandrel has a hexagonal thickness of 30mm Shaped resin honeycomb sandwich structure. Use Replicator or Cura slice software to divide the resin honeycomb sandwich structure to obtain the shape of each section, and generate the galvanometer motion code sequence sequentially. The Cute-Ⅶ photosensitive resin and carbon nanotubes of Shenzhen Baolimo Technology Co., Ltd. were placed in an ultrasonic oscillator, and oscillated for 1 hour to disperse. Pour the photosensitive resin mixture prepared in the previous step into the transparent glue tank 5 . Move the sample stage downward to contact with the bottom of the transparent glue tank 5 . The computer runs the Smart-I printing software developed by Shenz...

Abstract

The invention discloses a preparation method for a resin honeycomb sandwich structure and a composite material structure thereof, and provides a closed cell honeycomb structure and a honeycomb sandwich composite material structure prepared by the honeycomb structure to mainly solve the technical problems of reduction in mechanical performance of a conventional honeycomb sandwich structure under water erosion, complexity in a forming process and higher manufacturing cost. Specifically for the closed cell honeycomb structure, closed cell honeycomb units are structurally designed, a closed cell resin honeycomb sandwich structure is prepared by a 3D (3-Dimensional) printing technology, and the resin honeycomb sandwich structure is adhered to a composite material panel to form a composite material honeycomb sandwich structure by adopting a vacuum bag or resin transfer molding process. The preparation method has the characteristics of convenience, reliable product quality and reduction in the production cost, and a good foundation is laid for the application of the composite material honeycomb sandwich structure to the high-tech fields of aerospace, vehicles and ships.

Description

technical field [0001] The invention relates to a preparation method of a resin honeycomb sandwich structure and a composite material structure thereof, belonging to the technical field of preparation and application of composite materials. Background technique [0002] The structure of the honeycomb sandwich composite material is a sandwich structure in which the porous honeycomb material is used as the core material and the fiber-reinforced resin-based composite material is used as the panel. The composite panel has excellent mechanical properties; the honeycomb core material can evenly distribute the load, avoiding the damage of the panel due to stress concentration, so the honeycomb sandwich composite structure has excellent compression and bending properties. [0003] The honeycomb core material first appeared in the 1930s. The British Norman Debruyne designed and manufactured a hexagonal aluminum honeycomb structure. 111, F-14 and other aircraft use more than 70% of t...
