Sir, we made one sample tube by roll wrapped, we used intermediate module (390Gpa) but, couldn't achieve the required results. We can't increase outer diameter which is 42.5mm. Any other solution which we can try? Is there any concept of pre stressing of CF tubes?

Sir, Thank you for your reply. 1. In this case can we go roll wrapped tube. 2. Any suggestions on resin and curing temperature. 3. We used 240Gpa (35msi) 12k fibre.

Respected all, I am Sonukumar Sharma from Maharashtra India. we are working on high rpm CF roller (8000rpm), length - 1100mm, OD- 42.5mm, ID - 30mm. we have made tube ( web angle 14 degree, with intermediate hoop layer ) through filament winding but we couldn't succeed as deflection (required <0.2mm under 25kg load) at the centre of tube was 0.6mm under 25Kg load. could you help us.
