Every application requires a different working knowledge of how to formulate thermoset mixtures. When engineers create car tires, they must be very strong. When engineers make erasers, the mixture must be one that is very flexible. By learning how to make and optimize thermosets, students mirror chemical and polymer engineers who design new formulas for the multi-billion dollar plastics industry. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers design more flexible thermosets by either an excess or lack of sufficient amine in their reactions. Student groups make and optimize thermosets by combining two chemicals in exacting ratios to fabricate the strongest and/or most flexible thermoset possible. Students act as engineers to learn about the strengths of various epoxy-amine mixtures and observe the unique characteristics of different mixtures of epoxies and hardeners.
