Summary of membrane-based infusion processing

This study focuses on a new liquid molding process called VAP. The process adds a membrane to the SCRIMP process allowing uniform venting on the complete preform surface. It evaluates the flow behavior, membrane material and final material properties resulting from the process. Overall, the membrane approach provides a more robust process with the correct selection of the membrane material. [Pg.344]

The membrane layer has to be carefully selected to be compatible with the resin and process cycle times and pressure. Models have been developed to evaluate the effective permeability of the membrane as a function of its nanoporous structure and the resin-membrane interaction. The models can be used to evaluate the penetration time of the membrane or the allowable [Pg.344]
