Systems and methods for the fabrication of prepregs (102, 202) possessing enhanced ability for the removal of gases (302A, 302B, 302C) from within prepregs and prepreg layups (300) prior to and/or during at least a portion of consolidation and cure process to form composite structures are disclosed. In certain embodiments, perforations (204A, 204B) of selected configurations may be introduced into the prepregs prior to, during, and after layup. The perforations provide routes for gases trapped within and between the perforated prepregs and prepreg lay-ups to escape during consolidation and cure process, reducing the residual porosity within the resulting composite. For example, composites having residual porosities less than 10 vol. %, on the basis of the volume of the composite, may be achieved in this manner. |
