Tr-dimensiton composite geonet for drainage is made of a unique tri-dimension geonet adhibited geotextile on both sides. It has the property of geotextile (filtration function) and geonet (drainage and protection) and provide a function system “filtration-drainage-protection”. The core of net with its unique tri-dimension structure can bear higher compressing load in construction and remaiin the certain thickness, provide good water conductivity.

Typical Applications

Landfill drainage; roadbed and road drainage; railway drainage, tunnel drainage, underground structure drainge, the retaining back wall drainage, gardens and sports grounds drainage.

Features of products;

1. Exxellent drainage function, can bear long time high press road

2. High tensile and shear strength

3. Reduce the rate that geotextile embedding into the core of geonet, can protect long time stable water conductivity

4.Can bear more than 2000KPa compression load

5.Its anti-compression capacity is much larger than common geonet for drainage

  • Here we illustrate our recently published work wherein we show how to design and fabricate fiber composite materials using a hydrogel matrix using 3D printing. The materials and method may be used to generate biomedical implants and devices and we illustrate one potential application area.

    “A 2.4 meter diameter propellant tank made of composite materials successfully completed pressurized testing at NASA¹s Marshall Space Flight Center in Huntsville, Ala. The goal of this game changing effort is to provide a substantial weight and cost savings, not just a one percent or a five percent changes, but up to a 30 percent weight savings and a 25 percent cost savings over state-of-the-art metallic tanks. Independently, these savings are compelling, but together, they are game changing and will enable future missions to reach new destinations. The 2.4 meter tank is a major element of the Composite Cryotank Technologies Demonstration Project‹ a technology that is one of the top nine projects funded by NASA¹s Space Technology Mission Directorate, which is innovating, developing, testing and flying hardware for use in NASA’s future missions.”

    http://en.wikipedia.org/wiki/Cryogenics

    In physics, cryogenics is the study of the production of very low temperature (below −150 °C, −238 °F or 123 K) and the behavior of materials at those temperatures. A person who studies elements that have been subjected to extremely cold temperatures is called a cryogenicist. Rather than the relative temperature scales of Celsius and Fahrenheit, cryogenicists use the absolute temperature scales. These are Kelvin (SI units) or Rankine scale (Imperial & US units). The term cryogenics is often mistakenly used in fiction and popular culture to refer to the very different cryonics…

    http://en.wikipedia.org/wiki/Cryogenic_rocket_engine

    A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel or oxidizer, that is, its fuel or oxidizer (or both) are gases liquefied and stored at very low temperatures. Notably, these engines were one of the main factors of the ultimate success in reaching the Moon by the Saturn V rocket…

    Various cryogenic fuel-oxidizer combinations have been tried, but the combination of liquid hydrogen (LH2) fuel and the liquid oxygen (LOX) oxidizer is one of the most widely used…

    …As part of the Game Changing Technology Division within the Office of the Chief Technologist, work is underway on the Composite Cryotank Technologies Demonstration effort. The term “cryotank” refers to storage of super-cold fuels, such as liquid oxygen and liquid hydrogen.

    Here’s the weighty dilemma:

    Roughly 60 percent of the dry mass of a launch vehicle accounts for the fuel and oxidizer tanks. By using composite materials, a cryotank structure can be produced that weighs 30 percent less than aluminum—the current state-of-the-art…

    The Cure: Out-of-Autoclave

    “Our project was one of the original projects within the Office of Chief Technologist,” explains John Vickers, NASA project manager for the Composite Cryotank Technologies Demonstration effort at Marshall Space Flight Center in Huntsville, Ala.

    The project centers on fabricating tanks that incorporate design features and new manufacturing processes applicable to designs up to 10 meters in diameter. These tanks could be used on future launch vehicles, in space propellant depots and Earth departure exploration vehicles.

    A key to this innovative technological push, Vickers points out, is “out-of-autoclave”—a relatively new technology for composites. Out-of-autoclave curing composite manufacturing is an alternative to the traditional high pressure autoclave curing process commonly used by the aerospace industry.

    While it has widespread applications in producing aircraft with the material cured in large autoclaves, using composites for aerospace is a relatively new technology. “The downside of that is that autoclaves are very expensive,” Vickers notes, and they are energy-hungry machines.

    “So a benefit for not having to use the autoclave is that many other companies can join into the aerospace industry that, prior to this, could not,” Vickers adds. “Aerospace and lightweight materials…well, they go hand-in-hand…”

    Test Articles

    The project goal is to produce a major advancement in a demonstrated technology readiness; successfully test a 5.5 meter-diameter composite hydrogen fuel tank; achieve a 30 percent weight savings; and 25 percent cost savings, compared to today’s state-of- the-art.

    The cryotank work can benefit multiple stakeholders, Vickers observes, be it NASA, industry, and other government agencies.

    Vickers says that there are two milestone-making test article structures within his program, a 2.4 meter and the 5.5 meter diameter composite tank. “By the way, that 5.5 meter tank will be the largest composite liquid hydrogen tank that’s been designed, manufactured and tested,” he says…
