| 摘要 |
<p>This patent relates to composites comprising adjacent layers of a microporous hydrophobic layer and one or more supporting layers. The composites are capable of withstanding pressurization after exposure to ionizing radiation. The two layer composites comprise: (a) a layer of woven metal material or woven synthetic organic polymeric material, and (b) a microporous hydrophobic polymeric membrane. Three layer composites comprise: (a) a synthetic organic polymeric material having, after irradiation, an elongation less than 25 % after 100 hours under a load of 2.0 pounds per inch, (b) a compliant synthetic organic polymeric material, and (c) a microporous hydrophobic polymeric membrane. Devices comprising one of the described composites and a means of restraint which provides strain relief at the supporting edge are disclosed.</p> |
