Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, a heterogeneous intercalation composite structural plate for ultra-high-speed debris protection, including a crushing layer 1, a mitigation layer 2, and a capture layer 3. The crushing layer 1, the mitigation layer 2 and the capture layer 3 are arranged in sequence from outside to inside. Fragmentation layer 1 faces the attacking direction of space debris and is used to shatter the impacted ultra-high-speed debris. The slowing layer 2 is located between the crushing layer 1 and the trapping layer 3, and is used to support the crushing layer 1, and is also used to slow down the movement speed of ultra-high speed debris. The capture layer 3 is closely attached to the surface of the object to be protected, and is used to cooperate with the mitigation layer 2 to increase the use intensity, and is also used for secondary i...

Abstract

The invention belongs to the technical field of spacecraft protection, and in particular relates a heterogeneous intercalated composite structural board for superspeed debris protection. The inventionaims to research the heterogeneous intercalated composite structural board for superspeed debris protection, wherein different stages of superspeed debris collision are protected by means of characteristics of different materials. The heterogeneous intercalated composite structural board for superspeed debris protection is characterized by comprising a crushing layer, a buffer layer and a capturelayer which are successively arranged from outside to inside; the crushing layer faces the striking direction of space debris for crushing the collided superspeed debris; the buffer layer is locatedbetween the crushing layer and the capture layer for supporting the crushing layer and alleviating the moving speed of the superspeed debris; and the capture layer clings to the surface of a to-be-protected object for jointly acting with the buffer layer to enhance the using strength, and for intercepting the space debris secondarily and capturing residual kinetic energy.

Description

technical field [0001] The invention belongs to the technical field of spacecraft protection, and in particular relates to a heterogeneous intercalation composite structural plate used for ultra-high-speed debris protection. Background technique [0002] Facing the complex and severe space debris environment, the probability of various types of spacecraft being hit by micrometeoroids and orbital debris (MMOD) is increasing, which may reduce the performance of the spacecraft, shorten the service life, and even lead to catastrophic accidents. At present, Whipple-type protection configurations and some improved protection configurations based on protection mechanisms similar to Whipple protection configurations are generally used, such as filled protection configurations and multi-layer structure protection configurations. Relevant ultra-high-speed impact experiments and simulation studies have also been carried out to evaluate various enhanced protective configurations (such a...
