Technologies such as 3-dimensional multi-chip modules, micro-machined electromechanical devices, multi functional structures, miniaturized transponders, miniaturized propulsion systems, variable emissivity thermal coatings, and artificial intelligence systems are currently in research and development, and are scheduled to fly (or have flown) in a number of missions.
Composite structural armor (CSA) is a multi-functional structure that provides ballistic protection, stiffness and strength at minimum weight.
The radiation shielding effectiveness of the multi-functional structure with spot shielding plate was demonstrated by proton beam irradiation test.
In order to improve the thermal conduction capability, pitch-based carbon fibers were applied to facesheet of the multi-functional structure.
The grid-stiffened multi-functional structure can provide an array of available rooms for integrating multiple electronic circuitries into structure with ease.
The substrate fabrication process was proposed and the grid-stiffened multi-functional structure equipped with several electronics and interfaces was built up.
In this report, Selective Laser Melting (SLM) is used to build a Negative Poisson's Ratio (NPR) TiNi-based Shape Memory Alloy (SMA) structure, creating a multi-functional structure that could be used as reusable armour.
It will also use multi-functional structure packaging technology to combine load-bearing elements with electronic housings and thermal control, greatly reducing the mass of the spacecraft's cabling and chassis.
Innovative manufacturing technology has led to the fabrication of complex shape and multi-functional structures by using the concept of integrated and bonded unitized structural components.
A preliminary questionnaire indicated unanimous support for implementing multi-functional structures in place of traditional single-purpose ones.
These morphologies provide a combination of connectivity and low overall volume fraction that can significantly enhance the performance of many multi-functional structures.
