Imagine a material that can offer mechanical properties competitive with aluminum and steel but are at fractions of their weight – a type of material with that capability are composites. Composite materials are used for many applications such as aircraft structures, biomedical devices, racing car bodies, and many others for their capability of possessing more balanced properties (stronger, tougher, lighter, etc.) when compared to traditional materials. In this class, students will delve into the theory to design composite structures, processing techniques to manufacture them, and structural testing methods for validation. Starting from traditional fiber-reinforced composite materials, this course will also bring in new concepts such as nanocomposites and bioinspired composites.
