I am working for Bcomp, nice to see people on youtube working with our material! Small advise, try not to use peel ply on the surface, it has no real use if you don't want to glue something on it. Moreover you will minimize the resin used and the meniscus between the powerRibs and the substrate, thus maximizing the stiffness to weight ratio. Insider trick: you can heat gun the vacuum bag so it shrinks and matches well the powerRibs geometry. Looking forward to see your next project!

Its a neat product and I’m excited to try it on something thats an actual thing! I learned about the heat gun bag trick after I laid this one up and can imagine that a lot less resin will be used that way!

Hi there and thanks for the great video and all the great stuff you do! However, I see the powerRibs have somewhat misshaped for some reason - how about you drop us an email at media@bcomp.ch and we make sure to get you some new powerRibs. Also, as "olhey" mentioned below, you can get a better result without the ply - it's a perk versus carbon fibres with less consumables! Look forward to be in touch with you, and never hesitate if you have any questions. Keep up the great work!

Thank you for your offer - I'm excited to try using the powerRibs for something that isn't just a flat panel - and will definitely skip the peel-ply next time! My "sample" was from an offcut that had been around so it had probably been folded and handled roughly - and I didn't make much effort to make it nice. I'm going to check you your videos on how to use it and learn more before trying a real project. It is super interesting stuff and I am impressed by how much stiffness it adds to a thin laminate!

I’m in NY, I can’t seem to find Sicomin 810 for sale anywhere online in the US. There’s a distributor, but they don’t have 810, only Greenpoxy for snowboards.

Yes, it isn't easy! I bought this through T Composites (tcomposites.com) in NJ. They are (were?) a distributor... maybe the one you're already dealing with. It took a while to get for me, but I don't recall why. Maybe I got the last gallon! There are some alternatives. I understand Gurit now makes a high-bio-content epoxy but haven't used it.

TLDR: 1.) Don't use a peel-ply with this stuff. 2.) Make your vacuum bag plenty big enough. 3.) Make sure you don't trap any fibers under your barrier tape. It won't end well if you do. 4.) Don't be lazy.

Have you tried the grid as an internal layer?
@ExploreComposites4 ай бұрын
I haven't. My concern is that it would be very hard to get the top layer of fabric to go up and over each rib gracefully without a lot of bridging. A short-fiber chopped reinforcement might work well though.
@AhilMohan4 ай бұрын
@@ExploreComposites Ah true. The bridging, at the expense of a little extra weight might add significant torsional rigidity (much like bead rolling on a flat automotive panel). Hopefully vacuum bagging will minimise the effect. Might be worth experimenting with

Which underground do you prefer for a shiny finish? I can think of an aluminium plate... In addition to that, do you recommend any mould wax for an easy release? Or wasn't that even a problem? Nice video!
@ExploreComposites Жыл бұрын
Wax is always a good simple choice for a mold release, but it can be a problem where heat is involved and after a time you get build-up. Aluminum plate is excellent, but it's expensive! On these samples I think I used a teflon release film for the surface of a laminated work table. It doesn't require additional release - because teflon. Its great, but leaves a texture and is expensive - and doesn't handle contours well.

Fascinating use of bio based materials. Thank you for the demo! What was the resin and where were you able to procure it from? Does it say whether it's the type of resin which breaks down under extended high temps? (Thinking of the compostable plastics which break down in commercial composting operations.)
@ExploreComposites3 жыл бұрын
The resin is Sicomin Infugreen 801 which is a partially bio-derived epoxy. It will probably break down under high temperature but much higher than even the hottest compost. This is not biodegradable by any stretch but if you left it outside for a few hundred years it would probably disappear unless you looked really close - the UV would get the epoxy.

Hi! Thanks so much for the excellent video. Were you happy with the strength of the sheet? And do you think it is possible to do a hand layup reproducing what you did here with vacuum infusion? I cannot imagine this turning out well with the powerribs. Unfortunately I do not have access to the necessary equipment for vacuum infusion, hence the question.
@ExploreComposites3 жыл бұрын
I didn’t do any mechanical measurements but it is much stiffer with the powerRibs than without. Flax is hard to do wet layup with. I tried but it was very voidy and puffed with air. Can probably improve methods with changes but infusion is great - especially with the powerRibs.

hi weird question, but does the material leave itchy splinters like fibre glass and carbon fibre?

No, not the same itch but there can still be resin-coated splinters. Because the fiber is so much softer it is much more pleasant to work with.

This is cool! This flax might be the perfect material for my project. I hadn't heard of flax for laminating. Just now I searched the entire internet to find out more, but it seems the internet hasn't heard of it either! (Well, I did find one store selling something similar, and I messaged the Gurit people... I guess that's a good start.)

If you're in the US, Rock West Composites sells a 11oz twill. Easy Composites in the UK sells some too and ships international. I'm sure Gurit would sell you a roll, but I'm not sure about retail distribution. I'll try to find out. Europe is way ahead of North America in the bio-composites thing!
