Measurement of the contact electrical resistivity of the interface between two unbonded laminae of a continuous carbon fiber thermoplastic (nylon‐6) matrix composite during heating provides a method of thermal analysis that is sensitive to the glass transition and melting of the thermoplastic matrix. The phase transitions result in peaks in the resistivity, due to matrix molecular movement.
