Embodiment Construction

[0020] Such as Figure 1 to Figure 3 As shown, the mold body of an embodiment of the present invention is composed of multiple layers of high-temperature-resistant prepregs. The periphery of the mold body is provided with a plurality of positioning holes 4 for positioning the aramid paper honeycomb.

[0021] The principle is: use the ready-made composite material product forming mold (such as figure 1 In this embodiment shown, the product forming die 1) is used, and multi-layer high-temperature-resistant prepreg is compounded to make a simple pre-setting mold 2 of aramid paper honeycomb with special-shaped curved surface. Positioning holes 4 are provided to cooperate with electrician's clips to locate the aramid paper honeycomb. Using the above-mentioned simple pre-setting mold 2 of aramid paper honeycomb with special-shaped curved surface can replace the traditional steel mold, which is easy to manufacture and low in production cost. After presetting the aramid paper honeyc...

Abstract

The invention provides a special-shaped curved-surface aramid fiber paper honeycomb simple pre-shaping die and a manufacturing method. The simple pre-shaping die comprises a die body. The die body isformed by compounding multiple layers of high-temperature-resistant prepreg, and multiple positioning holes for positioning aramid fiber paper honeycombs are formed in the periphery of the die body. The manufacturing method of the simple pre-shaping die includes the steps that the die is formed through an existing composite product, and the multiple layers of high-temperature-resistant prepreg arecompounded. The simple pre-shaping die has the beneficial effects of being simple in structure, easy and convenient to manufacture and light in structure, compared with a steel die, the manufacturingcost is reduced by 80% or above, and the simple pre-shaping die has the technical effects that the pre-shaping treatment is easy to operate, and the attachment effect of the treated aramid fiber paper honeycombs and the curved surface of the composite product is good.

Description

technical field [0001] The invention relates to a mold, in particular to a simple pre-setting mold for aramid paper honeycomb with special-shaped curved surface used in a sandwich structure of composite materials and a manufacturing method thereof. Background technique [0002] In the prior art, aramid paper honeycomb core layer is usually used for structural reinforcement of sandwich materials of composite sandwich structure products. The sandwich structure of composite materials is mostly a special-shaped curved surface structure, and the aramid paper honeycomb is mostly a flat structure. Before the composite processing of the aramid paper honeycomb with a flat structure, the flat structure needs to be preformed to achieve a close fit with the curved surface of the composite material product, and to ensure that the aramid paper honeycomb is bonded to the curved surface of the inner and outer skins during the forming process Firm, no delamination. The traditional preformi...
