Embodiment 1

[0042] figure 1 As shown, Embodiment 1 of the present application provides a composite material reinforced bulkhead. like Figure 1-Figure 6 Reinforced bulkhead shown,

[0043] It includes a frame body 1, a foam core 4 and a reinforcing rib 1-1, the foam core 4 is filled in the frame body 1, the reinforcing rib 1-1 is supported in the frame body 1, and the frame body 1 It is composed of a composite material layup, and the composite material layup is provided with a reinforcing layer 7-3. The position of the reinforcing layer 7-3 on the inner surface of the frame body 1 is convex, and the reinforcing rib 1-1 is provided with a notch 1-1-1. Reinforcement layer 7-3 fit. The present invention solves the problem that the local structure of the bulkhead needs to be connected to products such as airplanes through the above solution, and the force characteristics of the local rigidity and strength of the bulkhead need to be satisfied, further increasing the function of stable conn...

Embodiment 2

[0048] Figure 7-Figure 10 As shown, Embodiment 2 of the present application provides a manufacturing mold for a composite material reinforced partition frame, including a base 5-2 and a chassis 5-3, and the base 5-2 is located on four sides of the base 5-3. Below the corners, the base 5-2 can be adjusted to adjust the level of the chassis 5-3, and rings 5-1 are set at the four corners of the chassis 5-3 to facilitate the lifting and movement of the mold as a whole. The mold is provided with polygonal protrusions 5-5 and circular protrusions 5-6, and the shapes of the protrusions are consistent with the shapes of the polygonal through holes 2 and the circular through holes 3 of the partition frame. Positioning pin holes 5-7 are provided on the outer mold 5-4 and the chassis 5-3 for positioning the corresponding positions of the outer mold 5-4 and the base 5-3, and then connected with bolts 5-8. The connecting holes of the positioning pin holes 5-7 and the bolts 5-8 are distri...

Embodiment 3

[0051] Embodiment 3 of the present application provides a method for forming a composite material reinforced bulkhead. By laying the reinforcing layer 7-3, the overall structural performance of the bulkhead and the stress characteristics of local stiffness and strength are enhanced. Specifically, the following steps are included: Figure 11 As shown, a layer of integral prepreg layer 7-2 is laid in the outer mold 5-4 and between the polygonal protruding parts 5-5, and a prepreg layer 7-2 is applied on the upper part of the circular protruding parts The prepreg layer of the notch is notched, and the prepreg layer of the notched layer is finally filled with the foam core 4 and the reinforcing ribs 1-1, and then covered and paved in layers; such as Figure 12 As shown, the position of the reinforcement layer 7-3 is positioned by laser projection, and on the basis of the above-mentioned layup, two prepreg layers are separately laid at the position of the reinforcement layer 7-3, a...

Abstract

The invention discloses a composite material reinforced bulkhead, a manufacturing mold of the composite material reinforced bulkhead and a forming method of the composite material reinforced bulkhead, and relates to the technical field of bulkhead structure equipment. The reinforcing bulkhead comprises a frame body, a foam core and reinforcing ribs, the frame body is formed by laying a composite material, and a reinforcing layer is arranged in the composite material laying layer. The manufacturing mold of the composite material reinforced bulkhead comprises a base plate, an outer mold and a base, and the base plate is provided with a protruding part consistent with a through hole in shape at the position of the through hole of the reinforced bulkhead. The forming method of the composite material reinforced bulkhead comprises the steps of overall laying of the composite material, laying of the reinforced layer and final laying of the part exceeding a pre-laying layer, and removing an isolating membrane, so that overall laying of the reinforced bulkhead is completed. The bulkhead has the advantages that the local strength and rigidity of the bulkhead are enhanced, the integrity is high, and the problems that the connecting strength with aircraft parts is insufficient, and the bulkhead is heavy are solved.

Description

technical field [0001] The invention belongs to the technical field of composite material partition frame preparation, and in particular relates to a composite material reinforced partition frame, a manufacturing mold for the composite material reinforced partition frame and a manufacturing method of the composite material reinforced partition frame. Background technique [0002] Bulkheads are generally used for the main force transmission and load-bearing structures of aircraft, pods, projectiles and other product structures. Traditional bulkheads are usually composed of edge strips, webs, reinforcing ribs and other structures, mostly steel, aluminum alloy, magnesium alloy and other metal structures. Affected by the process and the properties of the material itself, metal bulkheads have the advantages of heavy weight, low bearing efficiency, Not resistant to corrosion and other issues. In addition, the bulkhead needs to be connected with aircraft, pods, projectiles and oth...
