Abstract

A method to improve thermal performance of vascular composites by using a two-phase working fluid for isothermalization includes the steps of: manufacturing a vascular composite structure optimized for a design point; manufacturing a thermal back end sized for the application; integrating the vascular composite into a fluid loop; and evacuating and filling the fluid loop with working fluid to an amount resulting in two-phase operation at the design point.
