Embodiment 1

[0024] like figure 1 As shown, the crash board includes an impact layer 1, a buffer layer and an energy-absorbing layer 4, and the impact layer is made of spun fiber. The material of the energy absorbing layer 4 is a high molecular polymer. The buffer layer is a textile honeycomb structure sheet. Between the impact layer 1 and the energy-absorbing layer 4 is a buffer layer, and the buffer layer includes a first spunlace honeycomb layer 2 and a second spunlace honeycomb layer 3 . The thickness of the first textile honeycomb layer 2 is 5 mm, and the thickness of the second textile honeycomb layer 3 is 10 mm. One surface of the first textile honeycomb layer 2 is connected with the impact layer 1 by bisphenol A epoxy resin, and the other surface is connected with one surface of the second textile honeycomb layer 3 by bisphenol A epoxy resin. The other surface of the second textile honeycomb layer 3 is connected to the energy-absorbing layer 4 through bisphenol A epoxy resin, an...

Embodiment 2

[0034] In this example, on the basis of Example 1, the buffer layer is changed to a three-layer structure, and the buffer layer includes a first textile honeycomb layer, a second textile honeycomb layer and a third textile honeycomb layer, and the first textile honeycomb layer. , The second textile honeycomb layer and the third textile honeycomb layer are bonded by functional resin, and the materials of the first textile honeycomb layer, the second textile honeycomb layer and the third textile honeycomb layer are textile honeycomb composite materials. The thickness of the first textile honeycomb layer is 9 mm, the thickness of the second textile honeycomb layer is 10 mm, and the thickness of the third textile honeycomb layer is 8 mm. The other structures are the same as in Example 1. The thickness of the first spun fiber honeycomb layer, the second spun fiber honeycomb layer and the third spun fiber honeycomb layer in this embodiment may be a combination of 5mm-10mm.

Abstract

The invention discloses an anti-collision board and a manufacturing method thereof. The anti-collision board comprises a colliding layer, a buffer layer and an energy-absorbing layer, wherein the buffer layer is located between the colliding layer and the energy-absorbing layer; the buffer layer comprises two or three aramid honeycomb layers which are bonded via functional resin; each aramid honeycomb layer is made of an aramid composite material and has a thickness of 5 to 10 mm; the colliding layer is made of aramid fiber and bonded with the buffer layer via the functional resin; and the energy-absorbing layer is made of a high-molecular polymer and bonded with the buffer layer via the functional resin. The anti-collision board provided by the invention employs a totally-nonmetal anti-collision energy-absorbing structural board body, is light, has good energy-absorbing and anti-collision effect, can effectively protect the inner structures of a fuselage and reduces later maintenance cost for an airplane.

Description

technical field [0001] The present invention relates to the technical field of aircraft anti-collision systems, in particular to an anti-collision plate and a method for manufacturing the anti-collision plate. Background technique [0002] With the development of China's aviation industry, more and more aircraft are flying in the blue sky at faster and faster speeds, accompanied by major flight accidents caused by bird strikes, which occur more and more frequently. [0003] The anti-bird collision board is the last safety barrier to ensure the high-speed flight of the aircraft, and its anti-collision effect will directly affect the safety of the aircraft. At present, the domestic anti-bird collision plate technology is still in its infancy. The plate-making process and materials are a single aluminum plate and metal honeycomb composite plate. The material is heavy, and the anti-collision energy absorption effect is not good. Serious damage to the body structure and high mai...
