A Study on Warpage of Injection molded Fiber Reinforced Plastic Composities

사출성형된 섬유강화 플라스틱 복합재의 뒤틀림에 관한 연구(이론과 실험 결과의 비교)

The injection molded part shrinks in the process of solidification by the amount of the coefficient of linear thermal expansion multiplied by the temperature difference between the coefficient of linear thermal expansion multiplied by the temperature difference between the room temperature and the temperature at which the solid structure is formed in the mold And it is called warpage for this type of deformation that shrinkage are not uniform throughout the injection molded part. To predict warpage phenomena in the articles the results obtained theoretically from the change of mold temperature fiber content of composites have been compared with exsperimental results.
