FORMING OF CARBON FIBER REINFORCED PLASTIC BY 3 D PRINTING/DIELESS FORMING

Abstract
3D printing or dieless printing is becoming a most versatile method to produce different shapes of material and composites. The process of forming carbon fiber reinforced plastic parts using a 3D printer is developed to manufacture 3 dimensional mechanical parts. The 3D printing process makes easy for distribution of carbon fiber in different alienation and direction and thus different property can be made through 3D forming process of Carbon reinforced plastic. The different parts can be manufactured by sandwiching the carbon fibers between lower and upper plastic plates made by 3D printing and by heating the sandwiched plates. The strengths can be increased by thermal bonding of the carbon fibers and plastic plates. Also the strengths can be increased

With 3D printers, mechanical parts are manufactured by laying down successive layers of molten plastic without dies (Kumar, 2010). But the strength of the mechanical plastic parts is not equivalent to conventionally manufactured ones. It is desirable to increase the strength of parts manufactured by the 3D printers. The use of carbon fiber reinforced plastics increases in aircraft and automobiles industries. Most of carbon fiber reinforced plastics have comparatively simple shapes such as plates and curved shells, and it is not easy to manufacture three-dimensional mechanical parts. A 3D printing process of carbon fiber reinforced plastics enables a flexible manufacturing system, and the strength of mechanical parts is increased by inclusion of carbon fibers. In the present study, a dieless forming process of carbon fiber reinforced plastic parts using 3D printer was developed to manufacture three-dimensional mechanical
