Graphene Composites exceeds crowdfunding target for graphene bulletproof shields

Graphene Composites, a UK-based company developing graphene-enhanced bulletproof shields, has exceeded its crowdfunding target. GC attempted to raise £300,000 on Crowdcube, but ended up raising £510,680 (around 676,625 USD).

Once Graphene Composites had hit its crowdfunding target, the company sent out a message to its supporters saying: “Thank You - by investing in GC, you have not only invested in a company that should provide you with a healthy return and strong dividends, you are also enabling us to develop and deliver products that will truly improve the quality of life for many around the world. For example, our GC Shield active shooter protection in schools now, and eventually our Lightning Harvester renewable energy sources. Thank You, from all of us on the GC Team”.

Graphenest launches two graphene products with pre-order campaign

Graphenest has launched two products, based on a proprietary graphene production method, now available to pre-order with a campaign price for a limited time.

The first product is HexaShield, a graphene-based paintable coating for RF electromagnetic interference (EMI) and radiation shielding. It reportedly provides drastic weight reduction, and reduced manufacturing cost as compared to metals, while achieving the required protection for the Gigahertz frequency range.

Graphene Flagship partners present a graphene-enhanced leading edge for the Airbus A350

Graphene Flagship partners Aernnova, Grupo Antolin-Ingenieria and Airbus have produced a leading edge for the Airbus A350 horizontal tail plane using graphene-enhanced composites. As the first part of the tail plane to contact air, the leading edge is subjected to extreme temperatures caused by compressive heating of the air ahead of the wing. Thus, it must possess excellent mechanical and thermal properties.

“Aernnova supplied the resin to Grupo Antolin-Ingenieria who added graphene directly to the resin and applied milling forces,” said Ana Reguero of Aernnova. “This creates small graphene particles – an important step to get good graphene infiltration within the resin, avoiding unwanted impurities, such as solvents, which can alter the viscosity of the resin. It is important to maintain the correct viscosity of the resin to ensure the optimal outcome during the resin transfer molding of the leading edge.”

Versarien updates on AECOM collaboration

Versarien, the advanced materials engineering group, has announced that it has signed a supply agreement to provide Versarien's new graphene enhanced polymer range to AECOM for a current infrastructure project.

This supply agreement follows the collaboration Versarien entered into with AECOM, a US headquartered and Fortune 500 company. This collaboration covered a project that AECOM and Versarien have been undertaking involving the incorporation of Versarien's graphene nano-platelets into large scale polymer structures used in civil infrastructure projects, with a view to increasing their structural strength.

Perpetuus concludes successful trials of graphene-enhanced tires - with an average increase of 40% in wear resistance

UK-based Perpetuus Advanced Materials announced the completion of a "real world" road testing program of car tires enhanced with surface-engineered graphene materials.

Perpetuus graphene-enhanced tires testing

Over the last 6 months, Perpetuus graphene enhanced tires were fitted to high mileage, commercial light vehicles, which primarily travel on the UK’s A and B roads. The tests compared the graphene-enhanced tires with regular tires and monitored the performance of both tires. Perpetuus says that the tests showed that the graphene-enhanced tires produced an average of 40% increase in wear resistance over the regular tires.
