Flying-Cars Body Manufacturing Using Spraying Elastic Waterproof and Water-Absorbing Frame Fabric Method

摘要

This research discusses about the manufacturing method of flying-car's body. The contents of this study include literatures, research methods, and results. Focus of this research is on the technique of manufacturing flying-car's body by spraying the body frame that has been coated by elastic fabric. Two types of fabrics will be used in this study namely water-absorbing fabric and waterproof fabric. Mold ring is used as a body frame and the elastic fabric to form the surface is then sprayed by resin to make it harder. After the elastic fabric hardened then fiberglass will be added to strengthen the material. Then tensile test and stress analysis are performed to find out the strength and suitability of material. From the test obtained that GFRP (waterproof fabric specimen) has better strength than GFRFP (waterabsorbing fabric specimen) with tensile stress 5 [49] Kg/mm~2 [MPa], 2.26% elongation, and von misses 1.718e+008 N/m~2 while water-absorbing fabric with 4 [39] Kg/mm~2 [MPa] for tensile stress, 2.24% elongation, and von misses 4.007e+008 N/m~2. According to the experiment it can be concluded that this method only needs the cost around IDR 902,500.00 with easier and even faster for a car body manufacturing process.
