Lanxess develops a composite manufactured entirely from natural resources

Sustainability is an essential part of how Lanxess does business. It is centered primarily on climate protection, energy efficiency, and the circular economy. The company is forging ahead with efforts to use bio-based and renewable raw materials to conserve resources and ensure that its own production processes are no longer reliant on fossil sources. One good example of this is a new product in the Tepex range of continuous-fiber-reinforced thermoplastic composites.

Dr. Stefan Seidel, head of Tepex research and development at Lanxess explains:
“We have combined fabrics made from natural flax fibers with bio-based polylactic acid as a matrix material and thereby developed a composite manufactured entirely from natural resources. We are now able to produce it to a level of quality suitable for large-scale production,”

Low-density flax fibers

Flax fibers have a significantly lower density than glass fibers. The composites made with these fibers are thus noticeably lighter in weight than their glass-fiber-reinforced counterparts. The flax fibers are used in the form of continuous-fiber reinforced fabrics. This enables the biocomposites to demonstrate the outstanding mechanical performance typical of Tepex, which is based chiefly on the continuous fibers arranged in particular directions. The weight-specific stiffness of the biocomposite is comparable to that of the equivalent glass-fiber-reinforced material variants. Designing the composite components to suit the expected loads enables most of the force to be transferred via the continuous fibers. According to Seidel, “This ensures that the high strength and stiffness characteristic of fiber-reinforced plastics are achieved.”

To be used in cars, industry, electronics, and sports

When coupled with transparent matrix plastics such as polylactic acid, the reinforcing flax fabric yields surfaces with a brown natural carbon-fiber look. “This appearance highlights the natural origin of the fibers and the entire composite and creates added visual appeal in sporting goods, for example,” explains Seidel. In addition to sports equipment, the new biocomposite could be used in cars, such as for manufacturing interior parts, or in electronics for the production of such things as housing components.

Easy to recycle

Like the variants of Tepex based solely on fossil raw materials, the new biocomposites can be completely recycled as purely thermoplastic systems as part of closed-loop material cycles. “Offcuts and production waste can be regranulated and easily injection-molded or extruded, either alone or mixed with unreinforced or short-fiber reinforced compound new materials,” says Seidel.

In the medium term, Lanxess is planning to use other bio-based thermoplastics such as polyamide 11 and other natural and recycled fibers in the production of Tepex.

The first 3D printed parts on the moon

In 2021, North American 3D Printer Manufacturer AON3D will help Astrobotic become the first American lunar lander to soft land on the moon since Apollo 17 (Dec. 7, 1972).

The first 3D printed parts on the moon
READING TIME
2 minutes, 20 secondes

Onboard, hundreds of mission critical components and private payload ‘MoonBoxes’ will become the first 3D printed parts to successfully land on the moon.

The Technology
An industrial 3D printer for manufacturing strong, high-performance parts. The AON M2+ features a largest-in-class actively heated build volume that provides ungated access to thousands of applications and materials, including PEEK, PEKK, and ULTEM™.

Astrobotic Peregrine lander
Designed to deliver commercial payloads to the surface of the moon, Astrobotic’s Peregrine Mission One (PM1) is set land on the moon in 2022. The lander will be launched aboard United Launch Alliance’s (ULA) Vulcan Centaur rocket powered by a pair of BE-4 engines manufactured by Blue Origin, another AON3D customer.

The Parts
Prototypes
Full-scale Avionics boxes, relays, bus bars, connectors, and other mockups were printed in-house saving weeks in lead times at an order of a magnitude cheaper on a per part basis.

Electrical system components
Hundreds of fixtures and brackets replace metal components, ensuring avionics and electrical system integrity while reducing vehicle mass, enabling design freedom, and speeding production. Peregrine’s avionics perform all command and data handling for the lander.

MoonBoxes
The world’s first commercial payloads delivered to the Moon’s surface, including two minted cryptocurrencies, will be packaged in 3D printed boxes made from high-performance materials to reduce mass.

Kevin Han, CEO, AON3D said:
“In 1969, landing on the moon marked the pinnacle of human technology. Returning 52 years later with the help of 3D printing proves its readiness to revolutionize manufacturing beyond prototyping.”

Space/launch-grade requirements
Typical desktop 3D printing materials work great for visuel models but when mission-critical parts must perform under astronomical conditions, Astrobotic turned to the AON M2+ and high performance materials. Here’s what i takes for a 3D printed part to meet aerospace requirements:

Temperature: 260°F (127°C) to 280°F (-173°C)
Radiation: 200-1000x Earth’s surface
Vibroacoustics: 180 dB+
Non-outgassing under vacuum: CVC<0,1% an TM<1% per ASTM E595
High strength to weight ratio
Flame retardant
Chemically resistant

3D printed parts replace metal components
High-performance thermoplastics can withstand some of the most demanding applications while reducing vehicle mass. At the cost of $1.2m per kg to deliver a payload to the moon, Astrobotic was able to reduce weight by 50% weight on hundreds of aluminum parts with 3D printed thermoplastics. These thermoplastics are made in:

PEKK: A semi-crystalline high-performance material featuring very high stiffness, tensile strength, and impact resistance. Plus, PEKK can withstand continues operating temperatures of 250 – 260°C with low outgassing properties under vacuum.

ULTEM™: An amorphous high-performance material featuring many of the same characteristics of PEKK but varies in that it does not have a melting temperature, therefore only softens at high temperatures, giving it the ability to still hold electrical components in place.

Сегодня выпал первый снег, его полно.
Летит, блестит красивыми снежинками,
Они садятся тихо на мое окно
И тают,стекая по стеклу слезинками.
Ну, почему так коротка их жизнь-полет?!
Мне жалко хрупких, маленьких снежинок,
Хотя... спросить бы у того, кто не соврет:
- Как лучше - слезы по стеклу иль
под подошву кожаных ботинок?..

Первый снег это пространство живых систем в классической науке доминанта,означающий как временно господствующий рефлекс,он все равно расстаётся,он временный в данный момент .Доминанта есть общий принцип работы Природы,и она определяет освобождение для достижения наиболее важных целей.На этом моя милая Мариша я хотел бы закончить это послание,но у меня есть исключительно один,единственный вопрос,КАК ВКЛЮЧИТЬ ДОМИНАНТУ ТВОРЧЕСТВА.

Неплохо, коллега! Только почему стих один?
Ему же скучно. Думается, что снег 2008 года
давно растаял...☺
