This is the chemical name for a class of thermoset fibers commonly used make fireproof racing suits.
What are aramids?
The term for a material that has different properties when measured in different directions, like fiber-reinforced composites or certain 3D printed parts.
What is anisotropy?
This manufactured product, usually supplied frozen, can be used to simplify the manufacturing process of carbon-fiber composites.
What are prepreg sheets?
This additive manufacturing technique uses liquid polymer resin and ultraviolet light to build parts.
