Default Age and 80's graphite/composite frames?

Wondering about the effect of the years passing and the vintage (let's say 80's) graphite/composite frames. Not counting grommets, I have strung 80's frames that strung up well and played well for their owners. And I have strung up a few where the strings (even with good grommets) have sunk into the frame with a few hits. Likewise, I remember a composite frame that just could not take a 50 lb string tension without losing shape. Any thoughts on fiberglass or early graphite in general and loss of integrity? Any engineers out there or those who experience with many frames?
With graphite/composite frames, does age alone change the strength? Then does the frame play differently almost 30 years later?
Thanks - I just love the old frames and I see more and more rec players doing likewise...
