Abstract
Methods, apparatuses, and systems for making prepregs are disclosed. A method may include depositing a resin material onto a surface of a fiber bed and forming a number of discrete resin regions thereon. A distance between the resin regions may be measured to provide desired exposed portions of the surface to facilitate permeation of air through the exposed portions of the surface in a direction perpendicular to a plane of the fiber bed during a curing process of the prepreg.
