Title:
MULTIFUNCTIONAL BIONIC THERMAL PROTECTION STRUCTURE AND FORMING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/008603
Kind Code:
A1
Abstract:
Disclosed by the present invention is a multifunctional bionic thermal protection structure formed on the basis of the SLM technology. The multifunctional bionic thermal protection structure comprises surface layers and a functional layer, wherein the function layer is composed of tubular structures and internal microstructures, and tubes of adjacent layers are guaranteed to be crosslinked with a certain size so as to ensure firm connection of the structure. The present invention follows bionic principles and is based on the microstructural features of horsetail so as to design the novel multifunctional bionic thermal protection structure. When interacting with air flow, the multifunctional bionic thermal protection structure can bear the dual action of thermal load and shock load and can change the mode of heat transfer under the action of the functional layer. Compared with structures without microstructures, the multifunctional bionic thermal protection structure can significantly improve the thermal insulation and protection performance; besides, the functional layer can effectively relieve stress concentration in the structure and buffer part of energy during shocks so as to improve the shock resistance performance of the structure.
