Thermal Nondestructive Testing of Composite and Metal Parts Manufactured by Additive Technologies
Source abstract
Abstract
Abstract We describe the application of active thermal testing using optical heating and ultrasonic stimulation for products manufactured by additive technologies, namely, carbon fiber composites with impact damage and delaminations, construction wall panels with air channels and metal cylinders with continuity defects. The use of the thermal method is most effective in the case of materials characterized by considerable attenuation of ultrasound that prevents the use of standard ultrasound testing. It is advisable to detect discontinuities of small sizes using ultrasonic IR thermography, since in this case local temperature signals arise only in defective zones due to the friction of defect walls, while the temperature of the base material does not change.
