COMPOSITE MATERIAL WITH FAILURE DETECTION PROPERTIES

摘要

A multiple layer composite material having fluid breach detection features provides indication of a failure in a fluid barrier. The indication of breach of fluid is provided before failure of a final layer of the composite material. The multiple layer composite material includes more than one fluid impermeable layer with an intermediate layer sealed between the fluid impermeable layers. Failure of one of the fluid impermeable layers is detected by fluid contact in the intermediate layer. The intermediate layer includes a reagent and/or detection device to indicate that the fluid has reached the intermediate layer.

1. A multiple layer composite material comprising:
a first fluid impermeable layer; a second fluid impermeable layer; an intermediate layer sealed between said first and second impermeable layers; said intermediate layer having a reagent; and said reagent active with a fluid when the fluid contacts said reagent after passing through said first or second fluid impermeable layer.
