AC and DC Cure Monitoring through Release Films and Vacuum Bags

Cambridge, MA -- Lambient Technologies LLC, the leader in precision measurement solutions for the curing of advanced polymer materials, announces the release of a new application note discussing the challenges in measuring cure state in processes using release films and in Vacuum Assisted Resin Transfer Molding (VARTM) applications.

In composite manufacturing release films prevent the adhesion of parts to a tool. VARTM employs vacuum bags so that atmospheric pressure can compress a composite against a mold. Dielectric sensors typically must have direct contact with the material under test. By preventing contact, both release films and vacuum bags present challenges for dielectric cure monitoring (DEA).

In fact, a suitably designed sensor, such as the 1-inch Single Electrode Sensor from Lambient Technologies, can measure cure state through thin films and enable the use of DEA in a wider range of applications.

The document, written for engineering professionals working with resins in industries such as automotive, wind energy, and construction, offers a detailed analysis of the advantages of DEA in manufacturing and research and development. As the only method that can measure cure state in real time under actual process conditions, DEA lets users apply laboratory results directly to manufacturing processes.
