碳纖沒有疲勞問題，可無限期安定? 要不要看看碳纖反覆加壓的下場:
聽聽詹姆士卡麥隆(James Cameron)是怎麼評論碳纖的:
"They fail over time, each dive adds more and more microscopic damage. So, yes, they operated the sub safely at Titanic last year and the year before, but it was only a matter of time before it caught up with them."
"它會隨著時間而衰敗，每一次潛下去都會增加更多的細微傷害。所以，沒錯，他們去年和前年都安全的操縱潛艇抵達鐵達尼號，但出事只是遲早的問題。"
碳纖抗延展不抗壓縮，所以不適合做潛艇。那要不要回想看看，你的碳纖車架在顛簸路面上下震動時，是在反覆延展還是在反覆壓縮? 我off road第一個斷的就是碳纖座管。
