How do you join multiple carbon fiber aircraft parts together after making molds from 3D printed parts?
Hi everyone,
I’m interested in building a VTOL UAV starting from parts originally designed for 3D printing.
My idea is to:
- print the original parts in PLA,
- use them to create molds,
- then manufacture the final parts in carbon fiber composite.
The problem I’m trying to understand is the structural assembly process afterward.
For example:
- wing halves split into multiple sections,
- carbon tube support plates/bulkheads,
- fuselage sections,
- internal structural parts.
Once all these carbon fiber parts are finished, what is the correct way to join everything together structurally?
Do people usually use:
- epoxy adhesive only,
- fiberglass/carbon overlay laminations,
- internal sleeves/joiners,
- bulkheads,
- carbon patches over joints,
- or a combination of all of these?
I’m especially interested in understanding how to:
Join multiple wing sections together
Attach carbon tube supports to the wing structure
Connect fuselage sections without creating weak points
Build a structure that can handle VTOL loads and wing torsion
If anyone has experience with UAVs, RC aircraft, composite airframes, vacuum bagging, or molded carbon structures, I would really appreciate some advice.
Also, if you know any good YouTube channels/videos/tutorials about:
- composite aircraft construction,
- joining carbon fiber parts,
- molded RC aircraft,
- structural composite techniques,
please share them.
Thanks!
