Graphene Tyres and Graphene Brake Pads

Could Graphene Use Create A Distruptive Technology In Tyre Sector?

Almost every day, we see new applications emerging from graphene. The fact is certain; graphene is a disruptive technology that holds huge potential for commercialization. Graphene has abilities to open new markets and even replace existing materials or material technologies. A brand new application of graphene came out which is producing graphene tyres and brake pads.

In 2016 GraphChina (Graphene Innovation Conference); Sentury and Huagao launched their first electrostatic conducting graphene tyre on September 22nd. 2-3 weeks before the conference Sentury and Huagao officially announced their cooperation on the product.

During the press conference, Sentury’s engineers (which is branded with the Landsail moniker), revealed that the latest test data shows their graphene-enhanced tyre offers; 1.8 meters shorter stopping distances (6 % improvement on conventional technology), between 1.5 and 1.8 times conventional mileage, 1.5% improvement in rolling resistance as well as a 10% weight decrease. If these improvements are achieved – it seems that graphene began to be a wonder material in the tyre sector as well.

On the first week of August 2016, Sentury Tire and Huagao revealed that the companies produced their first trial production of graphene tyre in October 2015, the 245/45 R18 LS588@RSC electrostatic tyre.

Just one tyre and is that all? Apparently not. Back then, the production plan is 5 million units in the first five years with an output set to increase it to 10 million in the second five years. To quote the companies themselves: “Sentury and Huagao will lead the industrial revolution in graphene-tyre field”. However, Hengyu and Vittoria are also on the scene now (as well as others that have not yet put their heads above the trench), executing this ambitious vision will be quite a challenge.

The other commercialized example is bicycle tyre manufacturer Vittoria has added graphene to its tyres to improve their puncture resistance. According to company's senior executive manager Michael Marx; graphene makes the tyres lighter, with less rolling resistance and more grip - something which was impossible using existing compounds. The addition of this nanotechnology material results in a faster, stronger, more resilient carbon-composite material. Graphene-enhanced composites have 10-30% improved material properties. Tests carried out by Vittoria’s R&D engineers, confirmed by external laboratories, showed that introducing graphene into the rim’s carbon-fiber matrix has a great positive impact:

Graphene reduces temperature build-up

Graphene increases spoke-hole strength measurably

Graphene significantly improves lateral stiffness

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%) can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle.

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene ) is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
