i like this idea, it is what I had in mind, although you have already though about it, apparently.
I have PETG and TPU - I have printed clamps for 25mm carbon fiber tube before - in tension, TPU is very strong. I undersized the part, and use the screw to increase the tension, providing the clamping force. What are your thoughts of PETG vs TPU for this application? In your picture above, I would print “Purple” colored part from PETG, while “green” from TPU.
Did you post the Fusion 360 or STL files on another post? I think this would be a nicer setup than what I currently have. I use a Naish mast so I would have to modify it but I’ve got plenty of time this winter.
Hi, that is great to hear. I have some ABS as well, but sometimes struggle with the warping and shrinking, even with heated chamber. Usually have to scale the parts 101.6%!!
Hi Toto44,
Could you share your clamp stl files, please. I am using 63100 too, but on Cabrinha mast. I think your type of clamp can fit different profiles with minimum modifications.
I spent a week to make this. With a lot of patience and love :). My process was:
Day1: Face A
Day2: Face B
Day3: Face C
Day4: Face D
Day5: Face E
Day6: Thick epoxy resin coat
Day7: Topcoat.
Sanding before the next step and using masking tape to limit resin and fiber. I use Carbon fiber 200gsm and fiber glass 110gsm. Very important is clean the surface for the 2 last steps
You could also only laminate the outside of the duct. That‘s what I did. 160g CFK on the outside, much easier, no struts in the way. The struts I enforced with 3mm carbon tubes epoxid inside. Printed with holes and drilled out. Printed in ASA-X, was pretty strong.
Have you thought about using a cheap plug in blanket to wrap your glassed projects? I’ve used it and it seemed to work well. It’s also very economical.
