WIRELESS STRUCTURAL HEALTH MONITORING WITH ELONGATED CARBON FIBER OR MATRIX SENSOR

摘要

The invention supplies the opportunity of unifying in a unique body the ability of describing the structure damage and/or stress/strain state and the ability of bearing applied loads; it can be integrated in and/or integral with the structure which is to be monitored. The invention is realized by a composite material (A) in which an electrical conductor is embedded (B). Said electrical conductor is the sensing part of the invention, and it is electrically connected to an electronic circuit, also embedded in the invention (C); a possible electrical connection system (d) can close the electrical circuit. The electronic circuit (C) guarantees the ability of communicating to the external environment via a wireless system. Parameters are fonction of the load applied. A suitable external data acquisition system (L) is used. Sensing element (B) is made of carbon fibers or carbone particles and reinforcement (A) of polymeric resin or ceramics:
