Durable core paddles

I have issues with delamination with paddles. In six months, i have crushed the core of three paddles. My current paddle went two weeks before i started getting the dreaded thunk sound while driving and pressing the sweet spot sounds like crinkling plastic. My goal is to find a raw carbon faced thermoformed paddle that can last six months without serious change in play. Any suggestions? Why is it a problem now with the core failing prematurely? sandwich paddles could go over a year without getting deadspots where the core was failing?
