  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. Raw Material Processing Steps1. Preheat ADIPRENE K 1 gallon cans to 50°C (122°F). 1 gallon can requires approximately 8 hrs to reach equilibrium temperature.2. Apply mold release to mold. Preheat Mold to 115°C (240°F)3. Pour the entire gallon of ADIPRENE K into a can and stir with a spatula in a “figure-eight” motion to ensure homogeneity. Add any additional ingredients at this time.4. Fill the hot mold by pouring ADIPRENE K down the side of the mold. Pouring down the side of the mold will reduce air entrapment.5. Place filled mold into the 115°C oven.6. Allow material to reach 115°C for curative de-blocking and complete curing. De-mold times for small parts (0.25lb) require approximately 20 minutes.7. Optional - Post Cure for 16 hours at 115°C for optimum properties • Torayca M40J Carbon Fiber • Readily available/Free • Adiprene K X028 • Readily available/Free

  11. 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]

  12. Relative Speeds

  13. 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]

  14. 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)
