Thin-Metal Lined PRD 49-Ⅲ Composite Vessels

摘要

In this program a total of 22 -8" diameter PRD-49-III filament wound vessels were evaluated for burst strength and fatigue performance. Eighteen vessels contained a .003" (.0762 mm) thick 321 stainless steel liner for fluid containment while the remaining four had elastomeric liners. Six of the metal-lined tanks were burst tested at +70℉ (+21℃). The final vessel design with a metallic liner gave an average burst pressure of 2560 psi (17.7 x 106 N/m2) and an average per¬formance factor (PV/W) of 1.75 x 106 inch (4.45 x 106 cm).nTwelve metal-lined vessels were cycled at strain levels equivalent to 50％and 75％ of ultimate at +70℉ (+21℃). All these vessels leaked in a relatively few cycles (20-60 cycles) with failure occurring in all cases in the metallic liner.
