As fuel economy regulations in the automotive industry become tighter, many efforts have been made to reduce the weight of automotive structural parts. Carbon fiber reinforced composite is one of the promising lightweight material with superior mechanical properties for the applications to automotive industries which often require the fast production system of composite parts with low costs. It is important to predict any defects occurred by undesired preform deformations for improving production yields of high speed composite molding processes which have been widely used for mass production of carbon fiber reinforced composite parts. In this talk, efficient schemes were proposed to predict deformations of fiber preform by comparing the forces applied to the preform in a mold, and the predicted results were compared the corresponding experimental results. |
