1. Filament Winding Machine

2. Project Name – Filament Winding Machine Project Number – P09226 Project Family – Competitive FSAE Autosports Systems Project Leads – Shijo George (ME) – Alex Sandy (ME) Start Term – 2008-2 planned academic quarter for MSD1 End Term – 2008-3 planned academic quarter for MSD2 Faculty Guide – Dr. Alan Nye (Mechanical Engineering) Faculty Consultant – TBA (Dr. Ghoneim, Dr. Kempski) Primary Customers – Formula SAE, Mini Baja SAE

3. Filament Winding Machine Mission Statement: To develop a low cost, first generation filament winding machine which produces simple composite tubing that can be further developed by future senior design teams Roadmap Objective: Fundamental step in developing carbon fiber tubing to be used in space frame of Formula Racing vehicles

4. Objectives and Project Deliverables Test strength and stiffness of tubing Produce composite tubing Failure analysis of composite design Design and build a filament winding machine

5. 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. After the resin has cured, the mandrel is withdrawn Components produced include pipe work, pressure vessels, storage tanks, and helicopter blades
