Great research of the theory of sandwich panels. The first thing that came to mind after the breakage from my experience working with various composite materials is that you need to connect the top and bottom layers with a layer wrapping around, thus creating a I or U beam structure. This was exactly what your next sentence described. In the final panels I imagine using a strip of fiber in the gap between core panels would suffice, depending on the size of the core materials. A marine engineer would be able to calculate the amount of internal ribs needed, although a few ribs or knees external to the sandwich and internal to the vehicle would add a lot of strength as well. Looking very much forward to the rest of the project.
Great work and interesting as always. CAD can be minefield and a bottomless pit of hours spent. I was distracted by the bearded guy eating in the video on the second screen.
Are you worried about the foam core degrading if moisture seeps in or gets trapped during a repair? In my head foam + water just equals trouble... Also, on the foam core: Is there a plan for field repairs if the core shears? The patch repairs on the skins are probably doable, but as you've shown they are unlikely to fail first, while i feel the core would be rather difficult to work on. Or is the plan "make it so strong it doesn't break"?
1:30 - Do you have a fire in your closet? (Down near um, the seat of your chair). If so, it's probably a bit late to do anything about it. But perhaps worth a mention anyway.
Hi Alex. Not sure if you had already mentioned or disregarded? But have you considered 'Aluminium Honeycomb Core'? Maybe with a cloth layer with plenty of resin bonded to the core? 👍
I'm not sure I have the 50 years it's going to take for this project to come to fruition from materials testing to arctic journey, but if you keep wearing shorts, I'll try. 🤣
Adding more layers of cloth (carbon or glass) wont help you as much as making the foam stronger or thicker. if you want more strength out of your panels while still keeping them light you need to be looking at alternative foam cores. you should be right on the edge of the core failing and the skin failing to maximize weight to strength performance.
Shouldn’t the parts of this vessel that are going to be banging up against ice and rocks “just” be steel? I applaud your research and development efforts but building a hull out of composite does not seem like it will be ready to be banged about without eventual failure.
I'm not sure I understand this. Composites can be wildly strong and impact resistant. Steel isn't magic - it can fail and dent. And it's very very dense!
Have you seen the prices? Also, not really designed for liveaboard, or long range, or long water sections. Oh and rather boring for a YT channel that's into making things. I've been in a Sherp. Fine for a few hours of fun.
@@AlexHibbertOriginals do whatever YOU want. Shackleton was unenvious of his heroism. Designing a vessel with more than 1 seat is a different committment
Ey, my old comment isn't showing, so I'll reiterate: If you need someone who can potentially do some of your CAD requests for free, tell me and I'll send you my contact details

Can’t wait to see how things are gonna go and your build.
Im really glad your still doing a cool artic project! Hopefully you find good ground to stand on with this channel and good luck man! This is awesome!

Love how the ruler dramatically fell.
Oh I do hope there is a Bernard patch to be purchased 😁
There will, but I don't want to rush the style or design. I'll consult with you all first.....
Beware of your carbon footprint 😂😂

Ha, I like that at least one person notices the video on the second screen when I'm at my desk. @BeardMeatsFood is my guilty pleasure.
@AlexHibbertOriginals Thanks for answering.
I'd be happy to help out with some of your CAD drawings if you'd like them doing for free.
That's kind! Do send a hello via my website as and when
I'd like to chip in here too! Been designing military trucks for 4 years of my 8 year career to date

Good old Shitelink ferry. Were you surprised at the increase in prices from when you were a child?
I confess as a child I wasn't the one paying !

Yeah I've discussed Alu and aramid honeycomb with the tech sales team. Rather tough handling and pricing for this project.
you mean my Vespa is Alan Color? 🤩
Progress again :)

Perhaps you missed the part about the vessel/vehicle being light weight.

Why dont you just buy a Sherp and be done with it. OK maybe not, that would take all the fun out of it...and funds from the bank lol
I had though a Sherp would most of what you are asking, or be the base design of your requirements

@@AlexHibbertOriginals indeed. Theres always the the Hagglunds BV206. Probably more pricey and even less to do.
Allen wasnt capable of waiting outside ice-flows, and now u want to DIY a vessel to cross them? stick to dragging a bouyant sled bucko
