Trista Ma: Film-cooled composites for reusable high-temperature structures Trista Ma (11765786) Composite and hybrid materials Materials engineering not elsewhere classified composites fluid-structural-thermal multiphysics <p dir="ltr">This research asks whether a thin, deliberately-applied film of liquid, released through tiny perforations (holes) in a carbon-fibre composite panel, can protect that surface. Using a constant heat flux test rig, the panel's cooling performance is measured and compared against no coolant benchmark. Separately, the standard mechanical tests check how much the perforations weaken the material. The experimental finding has showed the cooling performance barely depends on hole size, but the composite develops small, localized hot spots that a simple panel-wide average hides, which happens on a real structure, where the failure occurs. The work combines infrared thermal camera and thermocouples (temperature)measurement, fluid behaviour of the cooling film, and structural testing to determine not just whether this cooling method works, but whether it is worth building into a real aircraft/spaceship skin. If so, at what mass and strength cost are we doing so?</p> 2026-09-29T23:54:47Z Image Poster 10.17608/k6.auckland.33825910.v2 https://figshare.com/articles/poster/Film-cooled_composites_for_reusable_high-temperature_structures/33825910 CC BY 4.0
