A novel injection process for long fiber composites using rotation

A recently-developed process to manufacture composite parts is described. The injection pressure is applied via centrifugal forces. The physical effects of rotation are arranged for both achieving very high injection rates compared to the RTM process and separating the embedded air from the matrix system. Pump technologies are not needed. The manufactured CFRP parts own a high fiber volume and low porosity content. The results promise an integration of this manufacturing technique in the industrial process chain.
