As you can see on his web site, Jimmy Yawn has done some experimenting with using PVC to make motors, but he wouldn't recommend that for others. PVC is frangible. It breaks into small pieces when it fails.

The motors he actually uses to launch rockets use non-frangible metal casings as required by the Tripoli Research Safety code.
