Functional Polymers and Composites for Zero Gravity

The current chapter focuses on the functional polymer and composite materials used for zero gravity applications. It discusses the various structures that are used in zero gravity (zero-G) and the material requirements for these structures. A structure in zero-G experiences harsh environmental conditions including the damaging effects of high vacuum, atomic oxygen (ATOX), radiations (ultraviolet and ionizing radiation), micrometeorites (i.e., space debris), and thermal cycling. The commonly used materials for zero gravity include polymers for thermal blankets or electronic components, adhesives, polymer aerogels, shape memory polymers, fiber reinforced composite materials, fiber metal laminates, protective coatings against atomic oxygen exposure and lunar dust adhesion, etc. All these materials have been detailed in this chapter and concluded with future trends in the domain.
