Title:
Systems and methods for measuring moisture absorbed in composites
Document Type and Number:
Japanese Patent JP6309530
Kind Code:
B2
Abstract:
Systems are provided for measuring absorbed humidity in a composite material, including an item of composite material which includes 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 fiber material, an insert embedded in the composite material, which is positioned in an interface zone between a first and a second ply of material, and in which at least one cavity is formed, in fluid communication with first and second ply of material, and an ambient humidity sensor positioned inside the cavity, capable of providing a signal indicating the humidity content in the atmosphere present inside the cavity. Corresponding methods are also provided.
