Abstract

The paper industry has used IR cameras primarily for troubleshooting, where the most common examples include the examination of the condition of dryer fabrics and dryer cylinders and the analysis of moisture variations in a paper web. Another application extensively using IR thermography is non-destructive testing of composite materials. This paper presents some recently developed laboratory methods using an IR camera to examine paper structure. Specific areas include cockling, moisture content, thermal uniformity, mechanism of failure, and an analysis of the copying process.
