Carbon fibre rod can it be cut down and used?

<< < (3/3)

PekkaNF:
Intresting choice of materials.

Extruded carbon fibre rod has usually pretty low fibre concentration, thus might not bear close to theoretical loads (I'm not going into matrices here). They take pretty well load on their longitudal direction, but if they have to take shearing or twisting, particulary if machined to a shape those pins are on the picture I would predict them failing. I'm not specialist, but I have a little hands on experience on model aeroplanes. I does not "looks right" to my eyes.

Hi there,

The turning torque will be around 5Nm-15Nm maximum.
The pin protrusion is 3mm so basically stubbies.
