How have you been going with winding angle selection? I understand the 90’ is optimal for burst strength (which many of you will use for rocketry), but I am generally trying to optimise bending stiffness. I started out using all 45’ plies which produced moderately stiff poles, however Turner passed on the following angles, which have helped a lot: 37/45/54.
Now I am trying to make thicker and stiffer poles I am looking to get some hints on additional fibre plies and their advantages. Also, does anyone know of software that might help determine ply angles for tubes like this?
