Abstract:
Carbon fiber reinforced polymers (CFRPs) are used in automotive and aerspace application due to their lightweight advantages. In order to improve productivity and reduce cost, it is necessary to develop composite complex functional component efficiently and effectively using injection molding. In this study, a complex functional CFRPs steering column support assembly was developed using injection molding. It was found that 30 wt% carbon fiber reinforced PA66 (PA66-30 wt%CF) was appropritae. Through topology optimization and mold flow analysis, the main warpage and shrinkage deformations could be controlled within 3mm. The CAE analysis results could be good agreement with the text results. The manufactured component can satify these performance requirments. Due to the excellent damping properties, the mode of the composite component can be lower at least 7 Hz than that of metal component. The weight of the component was 4.1kg, and the weight reduction was 4.2kg compared to the steel part. The rate of weight reduction was above 50% percent.
