Dynamic dielectric analysis: Development of techniques for following the curing process of laminating polyester resins
DDA measurements made over a wide frequency range with a novel sensor are used to determine the onset of reaction, variation in viscosity, onset of gel, and reaction completion in a series of peroxide-initiated unsaturated polyester resins diluted in styrene monomer. The dielectric measurements provide detailed insights into (he the cure process not available by conventional thermographic techniques.
