다국어 초록 (Multilingual Abstract)

Thermoplastic composite materials have considerable promise for increased use in low cost high volume applications because of the potential for processing by solid phase forming. However, the formability of these materials have not been well characterized. The primary focus of this research is the investigation of the bendability in pure bending. The materials tested contained 20, 35, and 40 percent by weight of randomly oriented glass fiber in a polypropylene matrix. The bending tests were performed at temperatures ranging from 75℃ to 150℃ and at punch speeds of 2.54 mm/sec and 0.0254 mm/sec. The bendability in pure bending is compared with prediction based on the simple analytical model. Good agreement between experimental and analytical results was observed. The bend ability map is presented as a good tool for identifying for good forming conditions as well as the visualizing the effect of forming temperature and punch radius on buckling.
