9 True or False Polymers that are used in FRP that are therm

9. True or False? Polymers that are used in FRP that are thermosetting are generally epoxy-based and these are not affected by continuous hot environments. (circle correct answer) 10. Draw a graph of strain versus time for a polymer under constant load, and show the 5 stages of the strain vs. time behavior. (1/2 pt. ea. identified)

Solution

9.

False.

Polymers that are used in FRP are generally epoxy based and epoxy has high strength and durability in continuos hot environment.

Hence, last part of given statement is wrong.
