Carbon Fiber Internal Pressure Vessels,
Abstract
Internal pressure vessels were designed, filament wound of carbon fibers and epoxy resin and tested to burst. Polymeric liners were used, and all burst testing was done at room temperature. The objective was to produce vessels with the highest attainable PbV/W efficiencies. The highest average efficiencies were 2,560,000 cm and 2,210,000 cm. These values compare favorably with efficiency values from good quality S-glass vessels, but strains averaged 0.97% or less, which is less than 1/3 the strain of S-glass vessels. Thus, the carbon fiber vessels are strain compatible with some liner materials at cryogenic temperatures, whereas the S- glass vessels generally are not. Efficiencies of the carbon fiber vessels were up to 60% higher than values for present metal vessels. Use of the carbon fiber vessels offers a significant weight savings potential for aerospace applica- tions. (Author, modified-PL)
