Investigation of impregnation speed depending on fillers during the manufacturing of parts by the vacuum infusion method

In the article examines the process of manufacturing three-layer carbon-fiber-reinforced plastic (CFRP) panels using the vacuum infusion method. A comparative analysis is conducted to assess the impact of various fillers on the manufacturability of the three-layer panel. Specifically, the study compares the impregnation speed of the part depending on the type of filler used. For the research, the layers of carbon fabric and filler were laid simultaneously before sealing with vacuum film. A comparison was made between the manufacturability of using a non-woven reinforcing material (Soric) and polystyrene foam (Airex).
