摘要

TO MAKE ONE PIECE OF COMPOSITE large-scale, and has a ratio VOLUMINICA HIGH FIBER (SUPERIOR S 58%), according to the technique of transfer molding resin, provides a method whereby strongly compacts a fiber preform (26) placed in a mold (20), WHILE THE rESIN FLOW WITH CONSTANT REFERENCE injected, while the pressure at the entrance INSTANTANEA MOLD is lower than a pressure reference. When it reaches this reference, the injection rate is reduced to maintain pressure at this level and TEMPORARILY REDUCE Compaction of the preform (26). SE rearranges the injection flow LEVEL FLOW INCREASES REFERENCE AND CONSTANT COMPACTION, to start a new cycle.
