- Explain the difference between thermoplastics and thermosets and how processing affects performance.
- Describe how composites are made (matrix and reinforcement) and common types such as fiber-reinforced and particulate-reinforced.
- Identify key advanced manufacturing methods for polymers and composites (e.g., additive manufacturing, molding, extrusion, and layup) and when to use them.
❓ Frequently Asked Questions
What is a polymer?
A large molecule built from repeating units (monomers) linked together; polymers include plastics, rubbers, fibers, and resins.
What is a composite material?
A material made from two or more constituents with different properties, typically a reinforcing phase embedded in a matrix to improve strength, stiffness, or durability.
What is the difference between thermoplastics and thermosets?
Thermoplastics soften or melt when heated and can be reshaped; thermosets cure into a rigid network and cannot be melted again.
What are common advanced manufacturing approaches for polymers and composites?
Techniques include additive manufacturing (3D printing), resin transfer molding, autoclave curing, and automated fiber placement to build complex parts with high performance.
