Method for measuring degree of cure of resin in a composite material and process for making the same

Image Number 2 for United States Patent #5142151.

A method for measuring the degree of cure of a resin in a composite material such as a prepreg. The method employs an infrared spectrometer device determining frequency absorbance information of selective frequencies which are representative of the degree of cure of the resin comprised within the prepreg. The method is adaptable for use in on-line production processes for the production of such composite materials.
