Destructive Chemical Inspections

Controlli distruttivi chimiciThanks to the machines in our possession we can perform in acceptance test and requalification of prepreg material (woven fibers, unidirectional roving, molding compounds from glass, graphite and Kevlar), paste adhesives, films, liquids and primers and quality control on the details of production.

In detail, we execute:

  • Volatile content in which to determine the difference in weight percentage of volatile material present in the sample analyzed.
  • Resin content by calcination of the glass fiber in which to determine the difference in weight of the amount of resin present in the sample, the weight of fiber remaining and any voids on the laminates
  • Resin content through dissolution with solvents or acids of the fibers of graphite and kevlar in which to determine the difference in weight of the amount of resin present in the sample, the weight of fiber remaining and any voids on the laminates
  • Gel time for the evaluation of the sample.Fluidity, density, expansion adhesives in paste or liquid film
  • Thermal analysis through DSC for the evaluation of:
    • Tg: the glass transition temperature
    • Tonset: the lowest temperature of the exothermic peak
    • Tmin: the temperature corresponding to the maximum emission of heat of the     exothermic peak
  • High-pressure liquid chromatography for quality control of resins
  • IR spectrophotometry
