Load Frame Lab room 107 EBU 2. This is the lab portion of MAE 20 designed for Freshman Aerospace Engineers. The structure of materials: metals, ceramics, glasses, semiconductors, superconductors, and polymers to produce desired, useful properties. Atomic structures. Defects in materials, phase diagrams, microstructural control. Mechanical and electrical properties are discussed. Time temperature transformation diagrams.The focus of this lab will be polymers and composites.
