  2. Background Why composite tubing? High Strength Light Weight High creep and fatigue performance Chemical and corrosion resistance

  3. Filament Winding • The process by which a continuous strand of impregnated fibers is wound onto a mandrel with specific fibers’ orientation which is controlled by computer. • Once resin has cured, mandrel is removed

  4. RIT First Generation Filament Winding Machine Capabilities • Produce tubes of limited dimensions • Simple to operate • Maintain tension every time • Limited range of orientation angles • Able to be expanded upon • Primary Goals • Learning Experience • New technology to RIT and students involved • Create simple but bulletproof machine

  5. Relative Speeds • Relative Speeds control the angle at which fibers lay onto the mandrel θ is the fiber winding angle (°) r is the radius of the mandrel Nm is the speed of the mandrel [RPM] Vc is linear velocity of the feed eye P is the pitch of the rack NS is the pinion speed [RPM]

  6. Relative Speeds

  7. Motors - Mandrel Τ is the torque applied [N-m] F is the force applied [N] r is the radius on which the force is applied [m] m is the mass of applied load [kg] g is the acceleration of gravity [9.81 m/s2]

  8. Motors – Feed Eye TL is the torque applied F is the force applied D is the diameter of the pinion η is the efficiency of the gear train (assumed to be .9) i is the Gear Ratio of the rack and pinion (1.5 in/rev)
