What is the composition of radar absorbing paint?
wikipedia saysOne of the most commonly known types of radar absorbing material is iron ball paint. It contains tiny spheres coated with carbonyl iron or ferrite. Radar waves induce molecular oscillations from the alternating magnetic field in this paint, which leads to conversion of the radar energy into heat. The heat is then transferred to the aircraft and dissipated. The iron particles in the paint are obtained by decomposition of iron pentacarbonyl and may contain traces of carbon, oxygen and nitrogen. Carbonyl iron is also used as a catalyst and in medicine as an iron supplement, even though it is toxic in higher doses.
What composites are found on mars?
water and air
What is the difference between synthetics and composites?
Composites means which is made of composition of two constituents where as synthetics is the combination of two or more parts, composites having constituents of different physical and chemical properties, where as in case of synthetics it can have same chemical or physical properties,in case of composites the ratio of material is maintained but it can not be in case of synthetics...e.g of synthetics is plastic, or composites is concrete
What is the Poisson ratio of carbon fibre reinforced composites?
It is 0.25
Do composites corrode?
Composites are typically resistant to corrosion because they are made up of different materials that can be chosen specifically to prevent or reduce corrosion. However, the specific construction of the composite, such as the type of matrix material used, can influence its resistance to corrosion. Regular maintenance and proper care are still important to maintain the longevity of composite materials.
How does the F-117 Nighthawk deflect radar signals?
The F-117 Nighthawk employs a combination of shape and material to deflect radar signals. Its unique angular design minimizes the radar cross-section by reflecting radar waves away from the source, rather than back to it. Additionally, the aircraft is coated with radar-absorbing materials that further reduce its detectability by absorbing radar energy. Together, these features allow the F-117 to operate with reduced chances of being detected by enemy radar systems.
What smart materials made in a stealth aircraft?
Stealth aircraft often utilize smart materials such as radar-absorbing materials (RAM) that can minimize radar cross-section, enhancing their invisibility to detection. These materials typically include advanced composites and coatings that can absorb radar waves. Additionally, shape-memory alloys may be used in control surfaces to optimize aerodynamic performance while maintaining a low observable profile. Lastly, temperature-responsive materials can help manage thermal signatures, further aiding in stealth capabilities.
Is there an radar absorption material available?
yes, I developed a radar absorbing coating , which can simply be applied on nearly every surface. It is very tough (passable) and reduces radar reflections between 5 and >110 GHz by 99 ... 99,99 %. [mailto:arrow33@gmx.de arrow33@gmx.de]

How does stealth technology work?
The goal of stealth technology is to make an airplane invisible to radar. There are two different ways to create invisibility:The airplane can be shaped so that any radar signals it reflects are reflected away from the radar equipment.The airplane can be covered in materials that absorb radar signals.
