    Sealing carbon fiber tubes for deep water application

    Well, we haven't finalized the tube material or size yet, just working with a few preliminary quotes. I assumed that the tube would be manufactured in long continuous sections with a fiber layup to suit our loading, then cut to our specific length. I'm not set on machining by any means. I just...

    Sealing carbon fiber tubes for deep water application

    Gbor, Obviously there are high external pressure loads to be resolved as well. That is a separate issue impacting the tube structural design. Thanks for your input. I'll look into the adhesive options.

    Sealing carbon fiber tubes for deep water application

    Thanks for the feedback. The o-ring groove seal is something I've considered, however the tube is tethered to a moving object via the end cap so the cap-tube joint will need to support about 100 lb of axial loading. Not sure if the o-ring press fit alone would handle that. Although perhaps...

    Sealing carbon fiber tubes for deep water application

    Hello, I'm looking for an effective way to seal a carbon fiber tube with a plastic (probably Delrin) end cap and o-ring. The tube houses electronics and is used in a deepwater application. I'm from a machine design background and would normally have a retaining feature (i.e.step or groove)...
