Abstract
Devices, systems, and methods of improving heat transfer between a composite wind turbine blade surface are provided to reduce cure time. The assembly includes molds having heating wires disposed proximate the mold surface for delivering heat to the composite blade during layup and/or resin cure. Additionally, the vacuum bag disposed on top of the composite part includes a plurality of fluid channels for distributing a thermal fluid (e.g. heated/cooled water, air or oil) across the composite surface (opposite the mold surface).
