An analytical model of the fluid permeability of glass ribbon-reinforced organic matrix composites is presented. The analysis indicates that such composites, with ribbon aspect ratios in the range 50 to 200 offer 100 to 1000 fold improvement in permeation resistance over fibre glass composites. This is pertinent to the application of composites for storage containers, pressure vessels, and pipelines. Permeation characteristics of glass ribbon composites were determined experimentally through mass spectrographic measurements of helium penetration. These measurements qualitatively supported the analytical model.
