Hey just a head up from another DIY Carbon Guy, since you infuse upwards with the resin below the part look at the MTI Valves for the resin intake line. They will keep the part under vacuum pressure and you wont have to bother regulating resin flow to avoid pooling, and the parts wont lose as much vacuum when the resin inlet line is opened to ambient air.

I smiled when I realised what that little room at the back of your workshop is.. a sort of poor-mans autoclave (oven, really, no above atmospheric pressure).. After installing the giant autoclaves at Premium Aerotek in Germany, my Dad went on to work with the teams doing exactly what you're doing - but on a giant scale - building carbon fibre Airbus airframes (A350 XWB).. laying out, bagging etc. The only difference is their layouts went on 70ft long, 22ft wide skids to be dragged into the giant 25m x 8m autoclave, making it expensive and annoying if the bagging failed! So thanks for surfacing some fond memories :)

Thanks for all these videos you published. I have noted that in making the hood in some cases you apply a clear coat on a mould before putting the first carbon layer for infusion and in some cases you dont. Is it really neccessery to apply clear coat? Does the applying a clear coat makes the outside surface more shine or? Thank you in advance for your answer!

@El.compa.chuy.21 Жыл бұрын
Love the content! Quick technical question… I’m not sure if this has been answered somewhere already but figured I’d ask. When it comes to the rigidity portion of carbon fiber panels, I recall years ago that some manufacturers would use aluminum/titanium rods as support and to add rigidity. Would doing something like that be beneficial or would it be best to just sticking with all carbon fiber with just carbon fiber reinforcement in those high stress areas? Thank you in advance!
@Birch1954711 ай бұрын
Don't know if you still need an answer to this question, but it entirely dpeends on why you'd need reinforcement. If you're looking for rigidity as you said, you will need some sort of brace that would span your contact points which you want to remain rigid. More layers of carbon will not offer this rigidity. Watch any video of someone lifting a fully carbon hood, it bends, carbon is incredibly flexible along it's flat axis, even with thick layers of epoxy.

I have a plastic boat that is made with upper/lower clamshell style pieces. Id like to split it and use it as a mold to make a CF version. Im wondering if i could do it for under a grand. I have service truck worth of tools but no vac or other related stuff. I use the boat for river adventures and its setup to row. Id want to incorperate some keel sheilding for landing and dragging/rock protection. I currently use hdpe patches that take hours to make. Boat is 10'x4'x36" & weighs about 140lbs from factory with foam blocks inside. Wondering where it would sit if made from CF.

This is the 2nd video of yours I’ve watched (subscribed now), and I’m curious of something. Wouldn’t you want the first layer to be as close to a single sheet as possible so you don’t have split lines or potentially mismatched strand orientation to the customer facing “show” side. I understand that some shapes make this impossible (likely). Just my curiosity.

@vikassm10 ай бұрын
No hard rule against it. But generally vaccum bagging is needed for lamination with minimal epoxy (weight savings). Clamps do a good job for glueing parts together. Using vacuum bags for glueing parts requires more effort, creates extra mess and a ton of wastage for no additional strength or weight savings! Then again, what do I know 🤣
