NaA zeolite membranes have been found a potential application in the separation of the small-sized gas molecules by molecular sieving and dehydration of liquid mixtures by pervaporation. However, there are some problems in the preparation in the NaA zeolite membranes such as the scarce support types, insufficient study on the synthesis rules and few literature concerning the NaA zeolite membranes preparation on the inner surface of the tubular support.

The results showed the maximum cyclic stress of CFRP bar should be under 70 percent of ultimate tensile stress; when the maximum cyclic stress decrease 5 percent of ultimate tensile stress, the fatigue life of CFRP bars increase generally 10 times; with the decrease of cyclic ratios, the fatigue life of CFRP bars decrease heavily; for the brittleness, CFRP bar should possess a higher reserve of strength, the margin of safety against failure is a necessity; according to experimental cyclic stress-fatigue life curve, the fatigue behavior of CFRP bar is much better than the fatigue behavior of Q235 steel.
