Abstract

The invention discloses a variable-component aluminum alloy high-strength and high-thermal-conductivity multifunctional integrated structure which comprises an aluminum alloy mounting boss, an aluminum alloy thermal management structure and a variable-component aluminum alloy transition structure, and an integral structure is formed through selective laser melting. The aluminum alloy mounting bossis used for connecting a carrier with a projectile body structure to form a main force bearing part of an integrated structure; the aluminum alloy thermal management structure is provided with a hollow inner flow channel and a flowing medium used for guiding heat to the area of the hollow inner flow channel in a high-power-density working environment; the variable-component aluminum alloy transition structure is located between the mounting boss and the heat management structure and used for achieving integrated connection of the aluminum alloy mounting boss and the aluminum alloy thermal management structure. The integrated structure has the advantages that the structure is simple, high-strength integrated connection of the two materials is achieved by adding the variable-component aluminum alloy transition structure, and the problem that the interface stress is large due to threaded connection or other indirect connection modes is solved.

Description

technical field [0001] The invention relates to a multifunctional integrated structure, in particular to a variable composition aluminum alloy multifunctional integrated structure with high strength and high thermal conductivity. Background technique [0002] The technical characteristics of the new generation of aerospace equipment are extreme service environment (high speed, high maneuverability, severe aerodynamic heat), extreme lightweight (weight ratio reduced from 30% to 10%), extreme integration (function integration, system integration), extreme high Performance (combat accuracy, detection ability order of magnitude improvement), the requirements for structural development are lightweight, high strength, high thermal control, and multi-functional integration. Materials are the main bottleneck restricting structural performance. As the performance indicators of the new generation of aerospace equipment have been greatly improved, the application of traditional materia...
