Abstract

The thermomechanical behavior of actively cooled composites in an elevated temperature convective environment is evaluated. Active cooling is achieved by pumping coolant through microchannels manufactured into the material to remove heat and reduce temperature. Vaporization of Sacrificial Components (VaSC) is used to create hollow microchannels in three-dimensional orthogonally woven glass-epoxy composites. The flexural modulus of the active cooled composites is measured using a four-point bend test at several environmental temperatures up to 325 °C. Material temperature on the surface and inside the composites is measured using thermocouples. Two channel architectures are compared, one containing channels at the specimen surface and one containing channels along the neutral bending axis.
