I have some questions about the carbon tub project:
1. What is the overall panel thickness, and what ply orientation/weave are you using?
2. What are you using as a core material?
3. What are you using as an insert material for threaded holes and localized attacment reinforcement and load bearing plates?
4. What adhesive are you using to bond sections together?
5. How are you dealing with corrosion if you are using metalic inserts and/or core?materials, what is your expected lifespan for the tub?
6. Are you curing at room temp or in an oven or autoclave?
7. Are you changing diapers too?
Cheers

I have a 10mm PVC plate the Bottom has 4 unidirectional diagonal layers,1 layer to the length and 1 to the side and 1 layer diagonal Aramid,The side of the tanks has a armid kevlar layer with possibility to let it sightable. on the upper side of the bottom i have now two layers diagonal.
the rest of the plates are all covered on both sides with 2 layers.And they will be enforced where its necessary.
To fit things on the chassis i cut out the PVC and i laminate some layers around or i put in a very strong gluelam like it s used in aircrafts.
for glueing special parts together we use 2K 3M glue.
For Fittings we try to do the parts changeable as easy as possible that we dont get some problems with corrosion.
We let it harden at normal room temperature.
And for the last question : What are diapers
i think laminating is easyer than changing diapers.
this week i build up the spider section so that we can laminate the spider
and the mono together next wheek.
after that we start with fitting frans parts on the chassis.
in 2 weeks we would do the load test with our first full carbon airplane fuselage.
3 weeks ago ! now i had a short baby brake
