any thoughts about polycarbonate for drivetrain?

I’m asking if it is ok to use polycarbonate for the drivetrain, and the some other parts that does not have a lot of load, we will use either 5mm or 6mm thickness. What are the advantages and disadvantages?

and if we give 10/10 rate for aluminum 6061, what will be the rating for the polycarbonate in this situation? (an FTC robot which I think considered not too heavy -mechanically-)
