Abstract
Composite prepreg including a gas venting network that allows multi-dimensional escape of gas from the prepreg during the curing process. Penetrable barriers are also provided between the matrix precursor elements to promote long-term storability of the prepreg at ambient temperatures. All or a portion of the gas venting network may be integrated with the penetrable barriers.
