Development of Optical-Based Mirrors For Space Telescope Using Aluminum Metal Matrix Composites An Overview

Abstract

Due to very low weight requirements, high manufacturing costs, and long lead times, monolithic glass being used to make huge, inflexible Segmented components for compact space-based mirror systems are at their capacity. To fulfil its needs in directed energy weapons, reconnaissance/surveillance, and encrypted communication, the Air Force will need to adopt new material solutions and production techniques. Metal, ceramic, and polymer composites, foams, and microsphere arrays are all examples of modern composite materials can be used to create mirror structural substrates with desirable properties such as Low density, high strength, stiffness, and toughness are tuned by CTE and modulus. Polishing these novel systems mechanically to meet aesthetic standards for figure and surface finish roughness is challenging because of the systems' multi-phase complexity. New replication and sol-gel or polymer spinning procedures will need to be developed in order to create the necessary optical finishes. During this test, we are employing stir cast techniques to make composites of Al 6061 and 7075 reinforced with graphene, silicon carbide, Beryl, Beryllium, graphite, MWCNT, and grinding and polishing to get the desired surface roughness.
