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

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from: https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread that i

Magnesium Oxide Nanoparticles/Nanopowder and Applications

General Information about Magnesium Oxide Magnesium oxide which has the chemical formula of MgO, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of Magnesium. It is a white powder at room temperature. Magnesium Oxide has very high melting point (2825 o C) and boiling point (3600 o C). Magnesium Oxide Nanoparticles/Nanopowder and Usage Areas Magnesium Oxide nanoparticles/nanopowder can be used in many different areas. For example Magnesium Oxide nanoparticles/nanopowder are used as a fire retardant for chemical fiber and plastics trades. For making crucible, smelter, insulated conduit, electrode bar, and electrode sheet Magnesium Oxide Nanoparticles/Nanopowder can be used as electric insulating material. Magnesium Oxide nan
