Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the web surface of the rib part is uneven due to the restriction of fiber slippage during the curing process of the rib part when the vacuum bag-autoclave method is currently used to manufacture rib parts with a flange height exceeding 50mm Defects, provide a method for manufacturing special-shaped composite material ribs that is not only simple in steps, but also easy to use, and can ensure that the web surface of the rib parts produced is flat

Embodiment

[0043] Such as Figure 2~6 As shown, the manufacturing method of the present invention needs to use two sets of tooling molds, one is a soft mold forming mold to prepare the soft mold 12, and the other is a part forming mold to prepare the rib part of the present invention. The rib part includes a web 1 and a flange 2, such as figure 2 As shown, the web 1 and the flange 2 are an integral structure, and the rib part is an axisymmetric structure.

[0044] The soft mold forming mold includes a support seat 4, and a soft mold forming male mold 3 for forming a soft mold 12 is also provided on the support seat 4, such as image 3 Shown. When a soft mold forming mold is used to prepare the soft mold 12, a rubber sheet is laid on the soft mold forming male mold 3, and the rubber sheet forms a rubber sheet layer. The rubber sheet layer in this embodiment is two layers. The rubber sheet is used to form a soft mold 12 with the same structure as the rib part, and the soft mold 12 is used to...

Abstract

The invention discloses a manufacture method of a special-shaped composite material rib. The manufacture method comprises the following steps: (1) preparing a flexible mold molding mold and a part molding mold respectively; (2) preparing a flexible mold by utilizing the flexible mold molding mold; (3) assembling a rib part blank and the flexible mold to a part molding mold to prepare a rib part; and (4) demolding. The manufacture method not only is simple in step, but also is convenient to use, and also can guarantee the levelness of a web panel of the rib part, so that the manufacture method is suitable for popularization and use.

Description

Technical field [0001] The invention relates to a method for manufacturing rib parts, in particular to a method for manufacturing special-shaped composite material ribs. Background technique [0002] At present, the vacuum bag-autoclave method is the most commonly used method for manufacturing high-performance composite parts. figure 2 The rib-shaped parts shown are often laid on a male mold and then cured on the male mold. However, when manufacturing rib parts with a flange height exceeding 50mm, the web surface of the rib part is usually uneven due to the limitation of fiber slip during the curing process of the rib part, and the thickness of the web surface is uneven, resulting in uneven thickness ,Such as figure 1 Shown. Summary of the invention [0003] The purpose of the present invention is to overcome the current use of vacuum bag-autoclave method to manufacture rib parts with a flange height exceeding 50mm, usually due to the limitation of fiber slippage during the cur...
