Problems solved by technology

[0003] However, the molding process and mechanical properties of fiber-reinforced polymer materials vary greatly, and the difficulty of manufacturing and processing varies greatly. Especially in some special high-end fields when pursuing extreme lightweight, the cost of materials and processes remains high, and even Failure to achieve part design goals
Because the metal alloy honeycomb structure can only be made into plates, and the surface layer is easy to peel off, it also limits its wider application

preparation example Construction

[0036] A method for preparing a combined honeycomb is characterized by comprising the following preparation steps.

[0037] 1) Prepare honeycomb strips, use several fiber reinforcements to connect two fiber vertical bars into one, and infiltrate and cure with resin to obtain honeycomb strips.

[0038] 2) The honeycomb body is prepared, and a plurality of honeycomb strips are cross-combined to form a honeycomb body.

[0039] 3) Honeycomb body filling, the honeycomb body and each honeycomb strip are filled with light resin.

[0040] 4) Attaching the surface layer, attaching the surface layer on the surface of the honeycomb body and then curing and molding to obtain a combined honeycomb.

[0041] Wherein, in the step 1) of preparing the honeycomb strip, processing of the mortise and tenon structure is also included, that is, grooves are made on the fiber studs so that they can be riveted and fixed with the cross-combined fiber studs. This can facilitate the cross-combination be...

Embodiment 1

[0052] Such as Figure 1-Figure 3 As shown, a combined honeycomb includes a honeycomb body 1 and a surface layer attached to the honeycomb body 1; the honeycomb body 1 is composed of a number of first honeycomb strips 2 and second honeycomb strips 3 that are arranged in crosswise combination; Both the first honeycomb strip 2 and the second honeycomb strip 3 are composed of two fiber ribs 4 and a plurality of fiber ribs 5 that are infiltrated and cured by resin, and each of the fiber ribs 5 is connected between two fiber ribs. Between the vertical ribs 4; the honeycomb body 1, the first honeycomb strip 2 and the second honeycomb strip 3 are all filled with light resin, so as to increase the overall strength of the components and to insulate heat and sound.

[0053] Wherein, the fiber ribs 4 are bidirectionally woven by fiber strips, and each of the fiber ribs 5 is parallel to each other and arranged up and down. The fiber ribs 5 can be a single fiber strip structure or multiple...

Embodiment 2

[0058] Such as Figure 4 , Figure 5 As shown, the combined honeycomb provided by this embodiment has basically the same structure as that of Embodiment 1, the difference lies in that the upper surface of the second honeycomb strip 3 is an uneven curved surface. In this way, the entire combined honeycomb surface is an irregular curved surface.

[0059] It can be seen from this embodiment that when it is necessary to obtain a combined honeycomb with a curved upper surface, it is only necessary to change the surface shape of the second honeycomb strip or the first honeycomb strip. The change of the surface shape of the second honeycomb strip or the first honeycomb strip can be realized by changing the shape of the fiber tie bars 5, which is very convenient to implement.

Abstract

The invention discloses a combined honeycomb and a preparation method thereof. The combined honeycomb comprises a honeycomb body and a surface layer attached to the honeycomb body. The honeycomb body is composed of a plurality of first honeycomb strips and second honeycomb strips which are arranged in a crossed and combined mode. Each of the first honeycomb strips and the second honeycomb strips is formed by infiltrating and curing two fiber vertical ribs and a plurality of fiber tie bars through resin, and each fiber tie bar is connected between the two fiber vertical ribs. The honeycomb body, the first honeycomb strips and the second honeycomb strips are all filled with light resin. According to different actual requirements, the shapes of the honeycomb strips can be very conveniently changed by changing the shapes of the fiber vertical ribs, so that the combined honeycomb with various parts of regular or special shapes such as a flat plate shape and a cambered plate shape can be formed through cross combination. The preparation method is simple and universal. A traditional forming process of a fiber-reinforced composite material part is thoroughly overturned, and the application field of the fiber-reinforced composite material is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of honeycomb structure, in particular to a combined structure of regular or special-shaped honeycomb and a preparation method thereof. Background technique [0002] With the advancement of technology, high-speed rail, urban rail and other rail passenger vehicles, aerospace manufacturing, shipbuilding, automobile manufacturing, wind power and other industries due to energy saving and consumption reduction, improved comfort, increased payload, and convenient transportation, etc. The demand for optimizing the weight reduction of the components of the equipment itself is becoming more and more urgent. For the weight reduction of functional components that are in great demand for equipment in various industries, there are currently two main ways: on the premise of meeting the design and use functions, the first is to use fiber-reinforced polymer materials instead of conventional metal materials to make solid core...
