REUSABLE VACUUM BAG

摘要

A vacuum bag (23) forming a vacuum envelope over polymeric materials being formed against a mold, has a fabric (55) (55) reinforced with flexible reinforcement fibers to withstand multiple mold cycles, and a chemically non-reactive and non-adhering material forming a release surface (60) separating the fabric (55) from a polymeric material being formed against a mold. The vacuum bag has a network of veins (79) or nubs (61) to distribute the flow of polymeric material.
