Embodiment

[0103] Example: such as Figure 1-Figure 10 shown.

[0104] First, based on the basic carbon fiber honeycomb panel 1, the central plug-in unit composed of carbon fiber honeycomb panels 2 and 3 is plugged up and down to form three evenly distributed honeycomb panels, and then the honeycomb panels 4, 5, 6, 7, 8, and 9 are plugged up and down in sequence, and then by analogy, the plugging of the entire honeycomb is completed from the inside to the outside.

[0105] Finally, select the appropriate structural adhesive for honeycomb adhesive process implementation. Structural adhesives must be fully suitable for the bonding of composite materials, can be cured at room temperature, have the characteristics of temperature resistance, environmental resistance and durability, small shrinkage after curing, and high tensile strength. The specific gluing method is: hand-held glue gun uses the mixing nozzle to directly inject glue at the joint of the plug-in board, and after it is complet...

Abstract

The invention relates to a carbon fiber honeycomb frame and an insertion connecting technology for manufacturing a carbon fiber honeycomb. The carbon fiber honeycomb frame comprises a basic carbon fiber plate, a center inserting connection unit and N inserting connection units from the first inserting connection unit to the Nth inserting connection unit, wherein the center inserting connection unit and the N inserting connection units are sequentially distributed from the center to the two ends of the basic carbon fiber plate. The length of the basic carbon fiber plate is determined according to the aperture D0 of a mirror to be manufactured, a plurality of inserting connection short grooves are symmetrically formed from the center to the upper end and to the lower end of the basic carbon fiber plate, the distance d between the adjacent inserting connection short grooves is equal to the edge length of a honeycomb hole, and the curvature radius of the basic carbon fiber plate is equal to that of the mirror. The carbon fiber honeycomb frame and the insertion connecting technology for manufacturing the carbon fiber honeycomb solve the technical problems that rigidity in the surface of a honeycomb is not uniform in an existing inserting connection technology, and implementation efficiency of an adhering technology is low. The insertion connecting technology is innovative from inside to outside, achieves up-down circulation, and is used for manufacturing the carbon fiber honeycomb.

Description

technical field [0001] The invention relates to a plug-in technology for making honeycombs, in particular to a plug-in technology for carbon fiber honeycombs. Background technique [0002] Carbon fiber composite material (CFRP) has the advantages of low density, high specific stiffness, small thermal expansion coefficient, large thermal stability coefficient, etc., and has good process performance, and the preparation process is quite mature. Using CFRP as the mirror body material of the optical mirror can produce a large-caliber, light-weight space optical mirror, which has great technical advantages in the field of space optical remote sensing. At the same time, in order to improve the rigidity of the mirror surface and ensure its surface shape accuracy and stability, the use of honeycomb reinforced structure is currently a feasible and effective means. [0003] Carbon fiber honeycomb can be designed and completed by winding and plugging. According to the current producti...
