Deformation Analysis for Compression Molding of Polymeric Composites with Random/ Unidirectional Fiber-reinforced laminates

무배향/일방향 섬유강화 적층매트를 갖는 플라스틱 복합판재의 압축변형 해석

Fiber reinforced composite materials are widely used in automotive industry to produce parts that are large, thin. lightweight. strong and stiff. It is very important to know a charge shape in order to have good products in the compression molding. In particular, the product such as a bumper beam is composed of the random and unidirectional fiber mats. This study analyzes numerically the characteristics of flow fronts such as a bulging phenomenon made by changing viscosity of random mat and unidirectional fiber mat and slip parameters. And it is discussed that the effect of ratio of viscosity A and stack type on mold filling parameters
