Hi everyone.
I'm just about to start the construction of a new telescope serrurier truss tube and need some advice. The picture is my 3D model of the design and i've decided to use carbon fibre for the design to a) make it as rigid as possible and b) as light as possible.
The circular parts need to be 6-8mm thick and i'm wondering if the following method is feasable for their construction. Using rectangular pieces of twill, arranged in a circle and built up to the required thickness which can then be cnc cut to shape (in yellow). I've never done compositing before so i'm wondering roughly how much twill would be needed to build up the thickness to what i need and will this method produce very rigid parts, bearing in mind that maintaining optical alignment is critical as the scope is purely for astrophotography. Thanks for any advice.
