Quick student answer
Which of the following is a common method for enhancing the properties of polymers?
Direct answer
Adding fillers to polymers can significantly enhance their mechanical properties, such as strength and stiffness, making them more suitable for various applications.
Key terms
- Composite Material: A material made from two or more constituent materials with significantly different physical or chemical properties, which remain separate and distinct within the finished structure.
- Lamination: The process of bonding layers of material together to create a composite material that is stronger and more stable than the individual layers.
Common trap
Confusing composites with alloys: Remember that composites are made from different materials that retain their properties, while alloys are mixtures of metals that form a new material.
