Resin cure monitoring system based on nondestructive dielectric spectrometry

  • Published:
Mechanics of Composite Materials Aims and scope

Abstract

An on-line indirect cure monitoring prototype system is described based on dielectric spectrometric measurements (frequency dependences of the dielectric modulus and/or dielectric permittivity and/or dielectric loss factor and/or relaxation spectrum). A key block of the system is the Dielectric Spectrometer. Model DS 7056-C interfaced with a standard PC. A variation of the dielectric frequency spectra during the cure process for two epoxy systems based on araldite resins LY556 and LY561-1 are considered as an illustration of capabilities of the described hardware and software.
