Anti-collision board and manufacturing method thereof

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...
