Biodegradation and Debonding Detection of Composite-wrapped Wood Structures

In this article, a methodology is presented for detecting biodegradation and debonding damage in composite-wrapped wood structures using a coplanar capacitance sensor. The presence of damage in the composite/wood interface alters the dielectric characteristics, causing a variation in the measured capacitance by the sensor. The theoretical background employed in developing the proposed capacitance technique is highlighted. A glass fiber …
