Fin - Glassing (For HPR L3 Build)

[eastvolt]

Based on your experience, do you think this would be sufficent as far as a L3 fin attachment?

0.375" Finnish Birch Fins
6.0oz Carbon Fiber 4HS (fin-to-fin)
3.5oz S-Glass Plain (fin-to-fin)
West Systems 105 / 206 Epoxy
Epoxy Fillets on all connecting surfaces (inside/outside)
Two Part Expanding Foam - internal

I haven't gotten FinSim yet, plus, i'm not sure if it can evaluate "glassed" fins.

Thanks
Dan

My L3 rocket has .375" thick fins and a layer of 6 oz 4hs glass on the fins itself and will have a layer of 3 oz tip to tip when complete.

However, the materials you choose and amount of actual required reinforcement depends on your fin dimensions. Small fins need less than big fins.
