Abstract : The effects of material and process variables on the fabrication and performance of biaxially loaded filament-wound external pressure vessels were investigated. Methods of establishing a standard test specimen were applied. Performance effects resulting from variations in material properties (e.g., resin content and viscosity index), processing parameters (e.g., tension, cure cycle, and overwrap pressure), and intentionally introduced manufacturing defects (e.g., interlaminar voids and gaps in hoop windings) were determined. Static, creep, and cyclic pressure tests were performed, and the interrelationships of voids, ultrasonic-absorption attenuation, interlaminar shear strength, and ultimate strength were analyzed.
