Fibre Glass Nose Cone Layup with 3D Printed Mold - NGNC-3
Вставка
- Опубліковано 20 тра 2021
- The Next Generation Nose Cone - 3 (NGNC-3) is the third successful attempt at generating a 1/3 scale nose cone as a proof of concept for the University of Victoria Rocketry Teams' subsonic competition rocket. The molds are annealed PLA for this scale setup, but will be sealed wood for the full scale videos to come.
The next layup is already in the works with accompanying video. NGNC-4 will incorporate changes to the wax cloth and vacuum bagging technique, as well as the incorporation of two new tools which were developed to help set the prepreg during the vacuum bagging and curing phase. Stay tuned for subsequent layups and videos.

This is awesome! Keep it up. Definitely want to give this a try at somepoint on my next scratch built rocket. Did you print the mold solid or with infill?
Thanks! The mold was printed solid so that I could anneal it and minimize any warping or shrinkage to preserve the shape during the annealing process.
Great video and very helpful! I was wondering how your progress on NGNC-4 is going and if you will be producing a video on that as well?
Hey there! I have moved on from the university team I was on with this project, and am not currently doing and rocketry. The team went on to compete with the full scale version of this with wood molds and it went great! I believe they got second in the competition: youtube.com/@uvic_rocketry9040

I don't understand why you didn't make the warhead directly in 3d printing?
First off, it is a rocket nose cone, not a warhead. There is no militarization or related purpose for this video, other than model rocketry, specifically for university teams.
Secondly, a solid 3D printed “nose cone” would be extremely heavy, and the heat generated by supersonic flow and/or sitting on a launch pad would soften the plastic.
The strength to weight ratio in comparison when laying up fiberglass with alternating (or some designed) pattern is much much much much higher than that of a 3D printed counterpart.
Specific to the direction you want of course
@@adambjohnson yes I had seen that it is a rocket nose, but in France we can call it warhead. I have built hobby rockets and created the nose of the rocket in petg using a 3d printer. I can tell you that it is very solid and light weight. The nose of my rocket is empty and the thickness is 2.5 mm if I remember correctly. beautiful life anyway.
@@dronie8782 thanks for the reply. I know PETG has great strength, and we have printed ours with PETG before, but this is a 1/3rd scale so the real version is very long and wide. A printed nose cone will add up the weight fast. A comparable printed version was 4x the weight.
Yes, 3D printing is fantastic for many things but this is not the purpose of this video or our work. The fiberglass is RF transparent (same would be for printed plastic), but again you are stuck with 105C glass transition for PETG or lower for other materials.
