A system includes a displacement-type capacitive sensor probe and at least one processor and at least one memory. The at least one memory stores instructions that, when executed by the at least one processor, cause the at least one processor to calibrate the sensor probe to a known dielectric constant of a first material, send an instruction to the sensor probe to measure a capacitive response of a composite article comprising the first material and a second material, receive the measured capacitive response from the calibrated sensor probe, determine, based on the measured capacitive response, an equivalent thickness of the first material in the composite article, and determine a percentage of the first material in the composite article based on the equivalent thickness of the first material and a thickness of the composite article.

Determining plastic or cellulose levels in composites

A non-destructive and non-contact test system quantifies the cellulose and/or plastic content in a given composite material board sample using capacitive sensors. The system includes a ground plate and a capacitive sensor probe system with programmed instructions to calibrate to a predetermined dielectric, determine, in a composite board placed in between the capacitive sensor and the ground plate, an equivalent thickness of material emitting the predetermined dielectric, and convert the equivalent thickness into a weight percentage of the material in the board.
