Dear Expert , I couldn't find part on the NASA website about this issue. I did a bit of a Google search, but I wanted to ask the experts here in order to access more accurate data.berkeman said:

Space suits are typically constructed from a variety of materials to ensure durability, flexibility, and protection. Common materials include nylon, spandex, urethane-coated nylon, and Dacron. The outer layer is often made of a material called Ortho-Fabric, which includes a blend of Gore-Tex, Kevlar, and Nomex for enhanced durability and resistance to micrometeoroids.
Space suits generally have a thickness of a few millimeters, typically ranging from about 3 to 10 millimeters. This thickness is necessary to provide adequate protection against the harsh conditions of space, including extreme temperatures, micrometeoroids, and radiation. The multi-layered construction helps maintain pressure, insulate the astronaut, and protect against potential hazards.
Books on space suits often discuss the engineering challenges of balancing flexibility and protection. They detail how multiple layers of different materials are used to achieve this balance. The inner layers are designed for mobility and comfort, while the outer layers provide protection. Advanced materials and innovative designs are employed to ensure that astronauts can move freely while staying safe.
Future space suits are exploring the use of advanced materials such as lightweight composites, enhanced polymers, and smart fabrics. These materials aim to improve the overall functionality of the suit, including better thermal regulation, increased durability, and enhanced mobility. Research is also focused on integrating new technologies like self-healing materials and sensors for real-time monitoring.
Space suit designs can vary significantly depending on the mission requirements and the environment. For example, suits designed for extravehicular activities (EVAs) in low Earth orbit may differ from those intended for lunar or Martian exploration. Lunar suits need to protect against abrasive lunar dust, while Martian suits must handle the planet's thin atmosphere and temperature variations. Each design is tailored to provide the necessary protection and functionality for the specific environment.
