Embodiment 1

[0028] see figure 1 , a rib positioning method for a reinforced panel, comprising the following steps:

[0029] a. Determine the position of the soft rubber mold 5 through the clamping plate. After the position of the soft rubber mold 5 is determined, mark the position of the lower backing plate 7 on the soft rubber mold 5, and mark the position of the lower backing plate 7 on the skin 1;

[0030] b. Take off the soft rubber mold 5 and the lower backing plate 7, bond the lower backing plate 7 to the soft rubber mold 5 with double-sided adhesive tape 9, and lay a layer of toughening film 8 on the skin 1, the toughening film 8 is located directly below the lower backing plate 7;

[0031] c. Assemble the combined lower backing plate 7 and rubber soft mold 5 on the skin 1 through the positioning clamp, and fill the core material 4 in the R area formed by the rubber soft mold 5 and the lower backing plate 7;

[0032] d. Use double-sided adhesive tape 9 to fix the upper backing pl...

Abstract

The invention discloses a rib positioning method of a reinforced wallboard, and belongs to the technical field of composite material preparation. The rib positioning method of the reinforced wallboardis characterized by comprising the following steps: a, determining the position of a rubber soft mold through a clamping plate, marking the position of a lower backing plate on the rubber soft mold,and marking the position of the lower backing plate on a skin; b, taking down the rubber soft mold and the lower backing plate, bonding the lower backing plate to the rubber soft mold through a double-sided adhesive tape, and laying a layer of toughening film on the skin, specifically, the toughening film is located under the lower backing plate; c, filling an R area formed by the rubber soft moldand the lower backing plate with a core material; and d, fixing an upper backing plate above the rubber soft mold by adopting a double-sided adhesive tape, laying a layer of toughening film on the inner molded surface of a rib except the brim sewing area, and assembling the rib on the rubber soft mold through a positioning clamping plate. According to the method, the rib can be firmly fixed to the skin, and cannot deviate in the carrying and sewing process, and the percent of pass of finished products is greatly increased.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a method for positioning ribs of a reinforced wall plate. Background technique [0002] The hat-shaped ribs and the skin are connected into a whole by sewing to form a prefabricated body, and then the composite material hat-shaped reinforced panel is prepared by resin film infiltration liquid molding, which can not only improve the interlayer performance and resistance of composite parts. Impact damage tolerance, and it is also a low-cost preparation technology, is currently widely used in the aerospace industry at home and abroad. When the ribs are stitched to the skin, the ribs need to be positioned on the skin to ensure that the position of the ribs does not shift. If the position of the ribs deviates during sewing, the position of the ribs will appear on the reinforced wall panel after curing. Deviations affect subsequent assembly. [0003] The contac...
