Notes:
To meet the high reliability of structural design and safety evaluation on carbon fiberwound reinforced polymeric (CFWRP) pressure vessel, the traditional safety factor design wassubstituted by reliability design based on the reliability theory and statistical principle. EightCFWRP pressure vessels were manufactured with the same material system by the same windingtechnique. And experiments were conducted to obtain the probabilistic distributions of designvariables. Results derived from reliability design (fiber thickness) agreed well with experimentalresults and were much lower than that from conventional design. Through comparison amongreliability design results with different statistics of fiber strength, significant effect of the variationof fiber strength on structural reliability of composite pressure vessel was demonstrated. Theconventional design was verified to be not reasonable since it considers only the mean value of fiberstrength without the effect of fiber strength distribution on structural resistance of pressure vessel
