  1. 1. Improving thermal fracture resistance in ceramic microcomponents for spacecraft propulsion

    University essay from Uppsala universitet/Ångström Space Technology Centre (ÅSTC)

    Abstract : Because of thermal transients and gradients occurring upon rapid heating or cooling, microcomponents made from High-Temperature Co-fired Ceramics (HTCC) often fail at temperatures far below what the materials can withstand per se. This work investigates how resistance to thermal fracture in HTCC microcomponents can be increased by improving the component design, aiming at increasing the thermal performance of a microthruster with integrated heaters.
