What are carbon composite bellows springs?

The Carbon Composite Bellows Spring (CCBS) from MW Components is a system of carbon fiber elements that combine to work as a high-performance, lightweight, and design-flexible compression spring meant to replace coil springs or metallic Belleville disc springs. A functional spring is made from several individual elements paired and joined to make a stack. The stack spring rate is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack. Applications include motorsports, aerospace, and high-performance activities.

Researchers identify effective materials for protecting astronauts from harmful cosmic radiation on Mars

Researchers have identified specific materials, including certain plastics, rubber, and synthetic fibers, as well as Martian soil (regolith), that would effectively protect astronauts by blocking harmful space radiation on Mars.

These findings could inform the design of protective habitats and spacesuits, making long-duration Mars missions more feasible. Because Mars lacks Earth's thick atmosphere and magnetic field, astronauts exploring the planet would be exposed to dangerous levels of radiation.

Dimitra Atri, investigator, Center for Astrophysics and Space Science and Group Leader of the Mars Research Group at New York University (NYU) Abu Dhabi's Center for Astrophysics and Space Science, and lead author Dionysios Gakis from the University of Patras in Greece, report these new findings in "Modeling the effectiveness of radiation shielding materials for astronaut protection on Mars," appearing in the journal The European Physical Journal Plus.

Using computer modeling to simulate the radiation conditions on Mars, the researchers tested various standard and novel materials to see which best shielded cosmic radiation. They determined that compound materials like certain plastics, rubber, and synthetic fibers would all perform well. Martian soil (regolith) was also somewhat effective and could be used as an extra layer of protection. In addition, they demonstrated that the most widely used aluminum could also be helpful when combined with other low atomic number materials. The study used real Mars data from NASA's Curiosity rover to confirm these findings.

"This breakthrough enhances astronaut safety and makes long-term Mars missions a more realistic possibility," said Atri. "It supports the future of human space exploration and potential establishment of human bases on Mars, including the UAE's Mars 2117 project and its goal of establishing a city on Mars by the year 2117."

"Several materials were specifically tested in a simulated Martian environment, making our results directly applicable to future missions and optimizing the combination of advanced materials with the natural resources available on Mars," Gakis added.

The researchers' conclusion in their paper included: "Our simulations suggest that the richer a material is in hydrogen, the more energy it absorbs. This is, however, only one of the parameters determining the efficiency of a substance against cosmic rays, another prominent one being the abundance in low atomic number elements. The most commonly used material in the aerospace field, aluminum, is not as effective as water, plastic, or compounds based on Li [lithium], but it still reduces a significant part of incoming radiation. We found that hydrogen and carbon-based compounds have an analogous behavior against cosmic rays, while materials made out of B [boron] or N [nitrogen] are not as helpful."
