    Wrap-up

This course will teach you composite materials, their components, manufacturing processes, and their applications. You will learn terminology, processes, datasheets, and criteria to select processes and materials. You will develop a laminate calculation spreadsheet, which will be a helpful tool for your future projects. After the course, you will be able to apply the knowledge acquired to use composite materials in manufacturing components and final products.
