SYSTEM AND METHOD FOR MEASURING ABSORBED HUMIDITY IN COMPOSITE MATERIAL Russian patent published in 2018 - IPC G01N33/44 G08B21/20 A61F13/42 

FIELD: measurement.

SUBSTANCE: group of inventions relates to measurement of humidity content in composite materials having a polymeric binder material. Disclosed is a system for measuring absorbed humidity in a composite material, characterised in that it comprises: an item of composite material comprising a plurality of plies of material consolidated through the action of pressure and heat, wherein each ply of material is formed from a resin matrix reinforced with a fibre material, an insert embedded in said composite material, which is positioned between a first and a second of said plies of material, in a limited interface zone, outside which said first and second plies of material are mutually contiguous, at least one cavity being formed in said insert, in fluid communication with said first and second plies of material, and an ambient humidity sensor positioned inside said cavity, and capable of providing a signal indicating the humidity content in the atmosphere present inside said cavity. Method for measuring absorbed humidity in a composite material is also provided.

EFFECT: higher reliability of measurements.
