Active Thermography in Qualitative Evaluation of Protective Materials [PDF]

open access: yesInternational Journal of Occupational Safety and Ergonomics, 2009
This is a study of the possibilities of a qualitative evaluation of protective materials with active thermography. It presents a simulation of a periodic excitation of a multilayer composite material. Tests were conducted with lock-in thermography on Kevlar composite consisting of 16 layers of Kevlar fabric reinforced with formaldehyde resin with ...
