Carbon Plastics for Aviation



Researchers have produced new substantially strong carbon plastics. They are based on phosphate binders that can hold up to 500°C. The findings are from the Institute of chemistry of Kazan federal University and the Kazan national research technical university. 

The work was published in the journal composites part a: Applied science and manufacturing.

Rustem Amirov is the chair of the department of inorganic chemistry and lead advocate research associate of the laboratory of polymer, smart materials and nano composites at the Institute of chemistry. 

He reports “composite materials are used very widely today: Almost everything is made from them, starting with hockey sticks and ending with airplanes. The vast majority of composites are created using organic polymer binders, which has many positive features, but have two significant drawbacks: They are flammable and work up to temperatures of 300 to 400°C maximum. At the same time, the use of composites, for example, in aviation or astronautics, And in many ‘earthly’ Areas, requires non-combustible materials, capable of withstanding high (Over 500°C) temperatures. We have solved this problem by using inorganic binders. The research used a new technique for creating carbon plastics.

The plastics are based on aluminophosphate and aluminochromephosphate. All of the binders are then reinforced with carbon fabric.

Amirov reports, “ We studied the logical properties, density, surface tension, and wetting ability of inorganic binders, and with this in mind, we developed optimal, impregnation regimes for carbon fabric. Drying and vacuum molding modes of carbon fiber, reinforced plastics were also developed. The physical and mechanical tests showed that the carbon fiber reinforced plastics obtained by high values of strength and elastic moduli in tension and bending.The method of dynamic mechanical analysis demonstrated high heat resistance of the obtained materials. The resistance of carbon fiber reinforced plastic to thermal shock was elevated by the change in the residual strength of carbon fiber reinforced plastic in bending.” 

The testing showed that aluminochromephosphate has the highest stiffness and strength. Products made from this material can be used in very high temperature conditions. Even some short term exposure to flames is tolerated!!

Amirov Summarizes, “Plastic on the basis of organic binders pollute the environment at its utilization. Our composite materials are eco-friendly and with decomposition they turn into components of clay and phosphate fertilizers.”

The future of aviation awaits this new discovery!

Mike Giradi from Stereotimes commentary on Holostage Room Treatments

I have been  friends with Mike Giradi for a few years and he has helped me test numerous designs .    I was so honored a few weeks ago when he agreed to give these Holostages a few words.  From. Mike G. The sound was a little closed in at first, but then it really opened up to prove it is another great audio product. The noise floor is greatly reduced. I am hearing details I've never heard before. When it's in the recording, the soundstage widens in all directions. The timbre of each instrument is spot on. The six Holostages installed in my room aided in the C13 alignment of air molecules to a far greater extent than the Bybee IQSE devices I had previously been using. Every instrument had greater depth, pop and presence. Listening to classical music on movie soundtracks is incredible now. The Holostages installed on my BACCH4MAC and monoblocks was the answer to what was needed. The noise floor dropped significantly in both cases resulting in greater clarity and music...

Queen Bee 🐝

  Bees hide an interesting secret. When the hive loses its queen, who alone is able to give life to the colony and maintain order in a perfectly organized society, all seems lost. The life of the hive slows down. Without new eggs, the future is lost. In a few weeks, the colony may be doomed. But the bees do not panic. Nor do they expect salvation from outside. Demonstrating extraordinary collective intelligence and profound instincts, they trigger spectacular emergency procedures, almost unimaginable in a world dominated by insects. --- ◆ The transformation begins with a simple but essential choice The worker bees choose common larvae - those who would normally be mere workers. They are nothing special. They are not born different. But their fate changes completely. They are chosen to receive a special food: royal jelly. A rare substance, produced by healthy bees, rich in proteins, vitamins and bioactive compounds. This is royal food in the purest sense of the word. The larvae fed ...

Novel Acoustic Wave Discovered

Image
  A new diffraction phenomenon was researched and published on January 14, 2025. The team was led by Tohoku University with collaboration from the Japan atomic energy agency and the RIKEN Center for emergent matter science. Surface acoustic waves (SAWs) are elastic vibrations. They travel along the surface of materials, not unlike ripples on a pond. SAWs are an important part of frequency filters used in every day devices like our cell phones. These devices change electrical signals in vibrations, or ripples. This occurs because of the piezoelectric  effect and it enables efficient signal processing. During this experiment, the team created a periodic array of magnetic nanoscale materials. The magnetic array is a sort of specialized grating that the waves passed through. The scientists were surprised. Instead of the usual symmetric defraction, the team saw something different. They observed a completely new, asymmetrical diffraction of SAWs called ‘non-reciprocal defraction’....
