Physics coursework!

I'm doing my coursework on Kevlar and struggling to find sources and i'm not sure what to write about.

Any suggestions? :confused:

You may want to talk about it's high tensile strength to weight ratio, making it a very useful material. Is it five times stronger than steel?

I think Tensile Strength can be calculated when you plot a stress against strain graph. Take the highest stress value as tensile strength?

Unparseable latex formula:

[br]True Tensile Strength = Final load value (from highest stress value before fracture) $\div$ Cross Sectional area of material[br]
