发明名称 Method and apparatus for vacuum assisted resin transfer molding
摘要 A method for vacuum assisted resin transfer molding a composite structure including fibers at least partially surrounded by resin using a mold including a tool having a surface shaped to correspond to the composite structure and an inflatable bladder for forcing the composite structure against the tool. A resin inlet is connected to a resin source for introducing resin into a mold cavity at least partially defined by the tool surface and the bladder and a vacuum port spaced from the resin inlet. The method includes the steps of opening the mold cavity, loading fibers into the open mold cavity, closing the loaded mold cavity, introducing resin through the resin inlet into the closed mold cavity loaded with fibers, and pulling a vacuum at the resin inlet and the vacuum port to draw excess resin from the structure prior to curing thereof.
