STUDY ON VACUUM INFUSION MOLDING PROCESS BASED ON A HIGH-PERMEABLE MEDIUM

The vacuum infusion molding process is becoming increasingly popular as a new type of Liquid Composites Molding Processes for the production of large composite parts with complex geometry. In the paper, the vacuum infusion molding process based on a high-permeable medium was investigated by experiments. The optimistic high-permeable medium was selected according to the visualization molding experiments and various factors that had influence to the mold filling process were discussed. Furthermore, the whole procedure is introduced in detail, taking the manufacture of a model boat in one infusion for a case.
