Materials

The materials used in space are, more often than not, the most advanced materials that humans have created and we are constantly researching and creating new and improved materials. These materials need to possess a number of unique properties to be effective in space.The CubeSat Structural Subsystem is made of a lightweight material that provides adequate interfaces to each other subsystem to ensure safe passage through all phases of the mission.

Commonly used materials

Kevler

One of the materials that often is able to fit the bill is Kevlar. Kevlar, a material used in bulletproof vests and armour, is an incredibly lightweight and strong material making it perfect for space travel.In addition to its high strength, kevlar also is incredibly resistant to temperature changes making it ideal for the orbiting structures that move in and out of the sun's direct heat as they orbit the Earth. Kevlar's toughness and durability also makes it ideal for protecting artificial satellites from dangerous orbital debris.

Aluminum

Another material that often used in space is Aluminum as it is light in weight. On its own, aluminum is not incredibly strong but when combined into alloys with other metals into it becomes much stronger.Aluminum alloys are often strong and lightweight enough to be functional in space structures and satellites. Aluminum is used for the shutters on the windows of the International Space Station in order to protect the windows from impacts.

PEEK(Polyether ether ketone )

PEEK grades offer chemical and hydrolysis resistance similar to PPS, but can operate at higher temperatures. Unreinforced, extruded PEEK offers good wear resistance and can be used continuously to 480°F (250°C). It can also be used in hot water or steam without permanent loss in physical properties. For hostile environments, PEEK is a high strength alternative to fluoropolymers. PEEK carries a V-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.
