Hi Steve,
Thank you for your thoughts.
It will be used as a type of oil pipe. On the inside, a steel pipe is used, which acts as a liner. Carbon fibre is used to make it lighter and to provide resistance against the external pressure.

Is an extra anti-corrosion coating on a carbon fibre filament wound pipe line, used on a sea depth of about
3000 m, required? And if so, what would be a good material?
many thanks in advance

Coating of carbon fibre epoxy pipe line in sea necessary?

The pipe is more than 10 m long, with a diameter of about 0.5 m. It encounters temperatures between -30 and +80 degrees Celsius. I don`t think there are strong influences of the edge on the total bond length capacity, is that correct?
We see unequal radial shrinkage as the maior failure...
Guys,
Thank you VERY much for the really valuable info.
To answer on some questions:
I am trying to predict the failure due to burst of the laminated pressure vessel. This vessel has only a partial depth cut, so not totally through-thickness.
The material properties I have are E11, E22, E33...
Does anybody has some experience with the finite element simulation of a cut (not a crack!) in the laminate of a carbon fibre/epoxy tank under internal pressure? The intention of the finite element model is to make a comparison between a tested construction (damaged CFRP tank under internal...
Hi GBor,
Many thanks already for the considerations you make.
The intention of the finite element model is to make a comparison between a tested construction (damaged CFRP tank under internal pressure upon burst) and the model. This to make prediction possible. I want to simulate a cut in...
Does anybody has some experience with the finite element simulation (MSc. Marc FYI) of a cut (not a crack!) in the laminate of a carbon fibre/epoxy tank under internal pressure? I used thick shell quad elements for the cylinder. At the position of the cut, I refined the mesh until the widht of...
Dear CompositePro,
You have a good point there. But I shall explain the problem a bit in more detail. The pipe is clamped on the outside, so on the composite material. On stainless steel (inner) liner, a pull force is exerted. The only load path to lead the pull force from the steel liner into...
Does anybody knows of/has good experience with an adhesive to bond a carbon/epoxy composite outer tube with a steel inner tube? Maior concern is the high temperature range of the construction, meaning the expansion of the CFRP and steel are very different. Under cold circumstances, the steel...
I am designing a subsea composite pressure vessel (mainly loaded under external pressure). Can somebody provide me information about the factors of safety that need to be applied. I suppose it most be more than 1.5, due to the underwater environment and the unknown influences it can encounter...
