Best 1467, I am sorry not to have replied sooner with regard to the weight of functionalised graphene used to obviate the need for a Faraday Cage; I do not know the answer. However,graphene also enhances substantially the strength of the composite material, so less of the host material is required. An example of this is the BAC Mono, a street- legal single seat high performance sports car built by Briggs Automotive Company; a new, lighter version, the Mono R, was launched at the Goodwood Revival 2019. This is from BAC's website :

"BAC has also incorporated its revolutionary R&D projects within the new Mono, using graphene-enhanced carbon fibre throughout the car. A world-first in every panel on the Mono R, graphene enhances the structural properties of carbon fibre to make panels stronger and lighter with improved mechanical and thermal performance."

From .gov website: "The Coronavirus Business Interruption Loan Scheme (CBILS) supports small and medium-sized businesses, with an annual turnover of up to £45 million, to access loans, overdrafts, invoice finance and asset finance of up to £5 million for up to 6 years."

This could be exactly what Hayd needs. In fact, with the above, there will be no need for a further fundraise. The only problem may be that the criteria for borrowings may be based on viability/existing turnover. Let's hope the current CEO and CFO explore the necessary options for the long term. In general, I've felt the Company is in better hands since that bellend Gibbs did one.

Pleasantly surprised about what they say about their cash position.
They highlighted in the interims the importance of reducing inventories especially in the US and let's hope that they have been able to do this.
Perhaps in the US, they can get the same good financing deal with the government that TRX did.
I continue to hold with a reduced amount.

Yes KNowt Great insight I had no idea that Weight of copper was used do you know what weight difference would be if Graphene is used.
I believe this tech will move into Mass Usages but it’s never easy you just need a large player to get involved and all of a sudden the snowball effect will take place it’s been a terrible investment for many up to now let’s hope the tide is changing

Yes knownowt

This seems like encouraging news and worth highlighting the Arden update that was also published this morning

The slow march to £5 starts now.....not !

I believe this to be a very important announcement, the implications of which are manifold and lifts Haydale to a superior level in the pantheon of Graphene companies. This agreement comes with an up-front licence fee.

"DLYB has been at the forefront of introducing and servicing high-end imported products for 15 years in China, which included the introduction of copper mesh for the purpose of lightning strike protection in both aerospace and wind energy sectors. It has obtained the international aviation quality management certification AS9120 and focuses on cutting-edge and high precision materials and technical solutions for aerospace, marine, railway, wind power, battery energy and industrial filtration industries. Using its existing experience and access to market, DLYB expects to use Haydale's electrically conductive graphene-enhanced masterbatch technology to develop and sell applications into these sectors. Examples of these applications are focused on electrical screening, control of edge glow and the development of lightning strike products for the civil aviation, defence, UAV and wind energy markets".

Interestingly, Airbus Industries has a very large presence in China and this announcement, allied to that of 4th November last year seems to have a common trend.

"Haydale has launched a range of graphene-enhanced prepreg material for lightning-strike protection, utilising functionalised nanomaterials to improve the electrical conductivity. The material has been developed in collaboration with Airbus UK, BAE Systems, GE Aviation and Element Materials Technology Warwick Ltd, within the NATEP-supported GraCELs 2[1] project where the first iterations of materials were developed and subjected to lighting strike tests".

Copper mesh Faraday Cages (used in composite aircraft) are not without weight mconsiderations - it is thought that the Dreamliner carries in excess of 3 tonnes of copper - so a switch to electrically conductive composites would alter significantly the operating efficiency of an aircraft.

My apologies; my final para should have begun: 'However, even distribution is unlikely to be achieved without functionalisation of the graphene'...

Maxi : Functionalisation is explained here www.haydale.com/technology/ under the heading HDPLAS PROCESS

[timbo003] 11/3/2020 19:07

Contrary to popular myth, Graphene/gnps suitable for functionalisation for subsequent use in conductive inks and composites are not an expensive commodity

[maxibrit2] 11/3/2020 08:59

so which is it - dispersion of graphite, which is a cheap and common commodity product, or dispersion of graphene, which really is not.

If you don't have graphene, nothing to functionalise - whatever that means.


..............
However, even dispersion of graphite is unlikely to be achieved without 'functionalisation' of the graphene which is where Haydale, with its globally (nearly) patented system, holds the aces - in my view.

[knownowt] 11/3/2020 01:23

Both Taiga and AMG provide graphite, very nearly pure graphite, which is the basic product from which is produced the 2-dimensional (one layer of molecules thick) carbon allotrope known as graphene. However, graphene is, in itself not a great advance on diamonds, (which are beautiful - so my wife tells me - but not 2-dimensional) unless it can be dispersed evenly throughout the host material. With even dispersion of graphene a plastic can become electrically conductive which is why Airbus, BAe, Cobham, amongst others, has been working with Haydale to see if the need for a 'Faraday's Cage' can be obviated in aircraft made of composite materials. Think of the weight-saving/ie.extra fuel capacity. (SEE announcement 1 Nov. 2019)

Obviously, de-icing is another possibility that can be achieved by electrically/thermally conductive composites.

The BAC Mono has incorporated its revolutionary R&D projects within the new Mono, using graphene-enhanced carbon fibre throughout the car. A world-first in every panel on the Mono R, graphene enhances the structural properties of carbon fibre to make panels stronger and lighter with improved mechanical and thermal performance.

You need to buy it and test first to find out it's not good - > I would assume ...

[meijiman] 10/3/2020 18:17

Thanks..not a holder more a watcher.

[timbo003] 10/3/2020 16:39

>>>>meijiman

As I recall they identified Talga as the best source of graphene for the conductive inks, as it's conductivity properties were superior to any of the others tested and I believe they use AMG graphene (sourced from Sri Lanka) for the composites (as used in the BAC mono and other composite applications), which is relatively easy to handle and has given consistently good results wrt improved mechanical and thermal properties of composites

[meijiman] 10/3/2020 14:36

How can they have any quality control if buying from different places even if its supposedly to a similar spec???

Repeat question

Where do Haydale source their graphene ?

I don't think they actually make it themselves - or do I have that wrong?


No you haven't got it wrong. Haydale do not produce graphene, they buy it in - even though they speak of it as if it's their own. They've bought from so many sources in the past, good and bad, (mostly bad according to their own past comments). I don't know who they are currently buying from.

Would be nice to break 1.8p

[lsoc85] 04/3/2020 21:53

Incredible to see some positivity on this thread. It's been doom and gloom for a long time!

I like the interim report. The top brass have made the position crystal clear - receipts are slow but payments have been cut.

There are fingers in several pies, inc any troll of this post's mum, and genuine fruition appears to be on the horizon.

Interesting that the two pieces of recent positive news weren't RNS'd like the previous management insisted on doing for every piece of info.

Also of note is that the positive news has followed a worrying interim report (re sales) quite sharpish.

Are they getting the price up as much as they can for a further cash raise - at circa 0.5p - or is it a genuine turnaround in fortunes? Is the hexagon flag of graphene finally flapping proudly in the corporate breeze of prosperity?

Praying for the latter; my house extension depends on it. :)

[niggle] 04/3/2020 15:55

Miss?

Pardon? why? Simply for asking for financial information for the contract announcements. Surely that's the most interesting part. I didn't know Winnefrith had even mentioned Haydale but it's a pretty obvious question.

Are you not interested? Otherwise, it's just empty news

[best1467] 04/3/2020 13:31

Also well and truly shafted here but noticed the RNS Ref EIS contract as a cyclist if this technology saves a few seconds per 1km 10 KM then it will be a major deal Cyclist at most levels are obsessed with Marginal gains and don’t care about the cost they said the test results were impressive in all sporting disciplines tested so as a consequence I had a nibble again yesterday
