High Performance Fibers Class Learning Objectives (CLOs)

Define strength in the context of materials.

Strength is a measure of a material’s resistance to permanent deformation or complete breakage under stress.

Explain what yield strength refers to.

Yield strength is the amount of force a material can withstand when pulled from opposing sides without suffering permanent deformation.

What is tensile strength and how is it different from yield strength?

Tensile strength is the amount of force a material can withstand when pulled from opposing sides without completely breaking. Yield strength is the force at which a material deforms permanently.

Describe the concept of crystallinity in relation to polymer properties.
