Composite Filament Winding Machine: P09226 Shijo George Christofer Brayton Alex Sandy Tiago Santos Daniel Weimann Project Manager Electrical Engineer Chief Engineer Mechanical Engineer Sponsored by RIT Mechanical Engineering Department
2
Project Description A machine to produce composite tubing (i.e. fiberglass, carbon fiber) Market: RIT ME Department Key high level customer needs / engineering specs: o Robust o Quality Control o Ease of use Simple but effective machine that produces limited products Minimize raw materials (resin, fiber) Maintain fiber tension throughout process Fiber volume fraction > 50% Operation procedure simple Easily disassembled for cleanup
3
Concept Description Creel to hold and tension fiber Resin bath to impregnate fibers Mandrel to wind fibers on Control system for accurate winding Separate Motors to drive spindle and carriage
4
System Architecture
5
Technical Risk Assessment Effective Impregnation System Description Fully impregnate fibers, but not soak Ensure quality of product Maintain constant temperature Mitigation Trial & Error Method with mock-up Resistance Heater or Hot plate to heat resin Monitoring System using thermocouples & sensors feedback Controllability of Motors Description Micro-controller compatibility Precise positioning of fibers Ease of use (set & forget) Expandable & Cost Efficient Mitigation Consulting with professors & technicians from suppliers Mock up with any available motors in Department Testing on Anaheim Automation motors
6
Current State of Design Sponsor obtained with fixed budget of $2,000 Design meets customer needs Design of machine elements completed, driving system & controls selected and unnecessary parts removed Part’s raw materials in house, machinery BOM prepared Design meets engineering specifications for full system and subsystems Project expenses within budget: So far ~ $ 1,000 allocated Behind one week in programming for system’s control Design of spindle’s motor bed still in process Mitigation: -Team effort in catching up with programming control routines -Team is working over the break
