The ability to remove the gas (302A, 302B, 302C) during at least a portion of strengthening and hardening process to form a composite structure and / or process prior to the in prepreg and the prepreg lay-up 300, improved prepreg (102, 202 ), the system and method of manufacturing a. In a particular embodiment, the perforations of selected shape (204A, 204B) the lay-up before, during and after may be introduced into the prepreg. Perforation to provide a path for the trapped between the inner perforated prepregs and prepreg layups and gases to escape during the hardening and curing process to reduce the residual porosity in the final composite. For example, a residual porosity of the composite is less than 10 vol%, based on the composite material by volume can be achieved by this approach.
