Ballistics Characterization Of Micro-Truss Reinforced Lunar-Inspired Geopolymer Concrete For Space Construction, Phoebe G. Johnson
Ballistics Characterization Of Micro-Truss Reinforced Lunar-Inspired Geopolymer Concrete For Space Construction, Phoebe G. Johnson
Honors Theses
This research investigates the ballistics response and compressive strength of a Fly Ash/ Lunar Regolith hybrid geopolymer concrete developed for space construction. The study aimed firstly to optimize the Fly Ash/ Regolith mix ratio for maximum mechanical performance and secondly, to evaluate the effectiveness of carbon-fiber micro-truss reinforcement, produced by 3D printing, in mitigating damage from high-velocity impacts. Concrete specimens with varying Fly Ash-to-Regolith ratios (100-50% Fly Ash) were fabricated and tested under compression and ballistic loading. Compressive strength tests followed ASTM C109 using a 110 Kip 810-MTS testing apparatus on both unreinforced and reinforced 2” cubes. For unreinforced samples, …
Lunar Manufacturing Systems And The Role Of Additive Recycling Technologies, Camille A. Newman
Lunar Manufacturing Systems And The Role Of Additive Recycling Technologies, Camille A. Newman
Honors Theses
Renewed international interest in sustained lunar exploration has created a growing demand for technologies to support long-duration space exploration. Part of the recent Artemis missions and the Moon to Mars initiative is to improve key mission capabilities and fill critical gaps necessary to sustain lunar habitation. Waste management, recycling systems, and manufacturing systems have been identified as critical technologies that need further development before a sustained mission is possible. This thesis explores the feasibility of an additive manufacturing and recycling system designed to process plastic waste generated during extended lunar habitation. Initial research focused on existing manufacturing and recycling technologies …
