Thanks, we have them all ‘in the can’ as they say so just editing and VO to do... so, hopefully, not long to wait.

Love it. Thanks for taking this one on.

I love this discussion between the designer and the user. The user clearly understands what the end product needs to be able to do, and the designer is taking those performance requirements and looking at the object and thinking through how to engineer and apply the materials at his disposal to meet the performance requirements. Great stuff!

Please keep up the videos!! Love the way you guys teach

Maybe at some point in the future we'll go more into the CAD side; in CAD terms, this is a very simple project. As many have pointed out, it's a bathtub really!

This is very interesting. When designing the sledge, you can turn it into a survival shelter by adding insulation to the sides & bottom and throwing a sleeping bag on top. In a storm, he could empty sledge and crawl in to survive.

Thanks for your support Anton, we appreciate your business.

In terms of what to use as the runners, as a skier i’d say go for a regular ski base material but if you can have it ground into a very fine pattern then it will run faster than a deep base grind, this is because youre running on very coarse snow so there wont be much water to wick away from the base compared to slushy or wet snow.👍🏻

At the temperatures designed and planned for, you don't benefit from any friction-generated film of water like you might at -10 or -15, C, so low dry CoF is the target.

Great

Surely low temp ski wax (paraffin wax) would be a good solution. PTFE and graphite coatings feel sticky on skis, but I suppose that's much warmer

Could you use a ceramic coating on the bottom for its hydrophobic properties to reduce friction?

hello id like to ask is there a formula or a relation to find out how thick will my part be after doing the vaccum resin infusion. ( for example how much does epoxy add to thickness of the reinforcment sheets). and thanks for the great and intresting content.

@easycompositestv

3 жыл бұрын

Yes, it's actually pretty straight forward. For many typical reinforcements (carbon, glass and Kevlar, to an extent) the thickness that layer of reinforcement will add to the laminate, in millimetres, can be correlated to its weight in gsm. So, a 200g cloth will add about 0.2mm thickness. A 400g will add about 0.4mm, an 800g would be 0.8mm. It's no exact but it's very close, especially for carbon and glass. Kevlar is a bit less dense and so works out a bit thicker than its weight would suggest.

Easy Composites must be very proud being involved in such a project. Congratulations are in order ; ) Elon Musk will undoubtedly be contacting EC very soon! TURK

Any rub-on products etc would wear off pretty fast. The product surface itself needs to be as fundamentally slippery as possible.

No, that's more of a fluid dynamics solution. Although you get a little surface friction melting as you slide over some snow surfaces, ground plastics would be there in the resin to hypothetically reduce the CoF.

@easycompositestv

3 жыл бұрын

It's difficult for me to understand the comparison really; if you're making a composite component (carbon, Kevlar, fibreglass etc.) they're you're almost certainly going to want a composite mould to make it in. It would be pretty-much unheard of to make a mould from sheet metal and wouldn't really be suitable if you did do it. If, on the other hand, you want a sheet-metal part then making a composite pattern wouldn't really make sense. If you're talking more widely about the comparison between composite vehicle panels and metal vehicle panels then the advantages are pretty-much all with composite panels, in terms of weight/stiffness etc, enabling you to make a lighter vehicle if it was made with a carbon fibre body compared to an aluminium or steel body, but the costs, especially in mass production, would be much higher for a composite body.

Whats this D material you guys talk about at the beginning?

I was thinking about a flexible skin with "ribs" on the inside, made of foam strips covered with CF to add the structure.

@@michaelbishton9439 I'll defer to the experts at Easy Composites, but although yes Diolen is exceptionally good at taking repeated impacts, it's a LOT less stiff than kevlar, carbon and glass, so if you need it to hold its shape reasonably, you need either quite some thickness, or to add a core, or carbon structure as you say. I'm not aware of any Diolen hybrid weaves to get a mix of properties like you can with carbon and kevlar.

They would be cylindrical ribs spaced six inches apart, from front to back. That way, if you bump the fairing, it would take the beating, but the overall fairing shape would be maintained by the ribs. Thank you for your thoughts.

There are not any hybrids at present however you can put different layers of different cloths to get a mixture of properties in the laminate, so carbon for stiffness and diolen for impact resistance. Aramid is even better for impact resistance and is commonly available in a variety of hybrid formats.

Only in spirit and love for Kevlar.

Why hasn't carbon fiber and kevlar been used yet ? When it comes to strength and impact resistance carbon fibre and kevlar are used to stop bullets from entering somebody's body cavity so I think it would be My personal option when it comes to strength and weight For regular civilians you not gonna get much better. There are Alaskan cub planes that are made out of purely carbon fiber/carbon cub lol The only downside is the cost of carbon fiber/1 tine intinial investment but the upside is it will last forever. Look at broadhead penetration That's exactly what hes talking about essentially penetration.
