REGULAR PREPREG, WIDE BAND PREPREG AND ORDINARY WET WOUND PRESSURE VESSEL STRENGTHS COMPARED AND THE EFFECTS OF PROOF TESTING ON VESSEL STRENGTHS

Abstract

DESCRIPTORS: *Pressure vessels, *Filament wound construction, *Laminates, Tests, Loading, Moisture, Pressure, Resins, Mechanical properties. A series of laminated pressure vessels was wound with regular prepreg, wide band prepreg and with wet roving. The results indicate no significant increase of strength of wide band over ordinary prepreg though the vessels made with wet winding indicated a significant increase in strength in 2 rolls out of the 3 used. The effects of holding the preload pressure at 80% of burst for a minute significantly reduces the strength compared to merely giving the vessel an instantaneous preload of 80%.
